Abstract
Despite their diverse functions, proteins are inherently constructed from a limited set of building blocks. These compositional constraints pose significant challenges to protein research and its practical applications. Strategically manipulating the cellular protein synthesis system to incorporate novel building blocks has emerged as a critical approach for overcoming these constraints in protein research and application. In the past two decades, the field of genetic code expansion (GCE) has achieved significant advancements, enabling the integration of numerous novel functionalities into proteins across a variety of organisms. This technological evolution has paved the way for the extensive application of genetic code expansion across multiple domains, including protein imaging, the introduction of probes for protein research, analysis of protein-protein interactions, spatiotemporal control of protein function, exploration of proteome changes induced by external stimuli, and the synthesis of proteins endowed with novel functions. In this comprehensive Review, we aim to provide an overview of cellular and biophysical applications that have employed GCE technology over the past two decades.

Abstract
Deciphering ubiquitin proteoform signaling and its role in disease has been a long-standing challenge in the field. The effects of ubiquitin modifications, its relation to ubiquitin-related machineries, and its signaling output has been particularly limited by its reconstitution and means of characterization. Advances in genetic code expansion have contributed towards addressing these challenges by precision incorporation of unnatural amino acids through site selective codon suppression. This review discusses recent advances in studying the 'writers', 'readers', and 'erasers' of the ubiquitin code using genetic code expansion. Highlighting strategies towards genetically encoded protein ubiquitination, ubiquitin phosphorylation, acylation, and finally surveying ubiquitin interactions, we strive to bring attention to this unique approach towards addressing a widespread proteoform problem.

Abstract
Since Strahl and Allis proposed the "language of covalent histone modifications", a host of experimental studies have shed light on the different facets of chromatin regulation by epigenetic mechanisms. Initially proposed as a concept for controlling gene transcription, the regulation of deposition and removal of histone post-translational modifications (PTMs), such as acetylation, methylation, and phosphorylation, have been implicated in many chromatin regulation pathways. However, large PTMs such as ubiquitylation challenge research on many levels due to their chemical complexity. In recent years, chemical tools have been developed to generate chromatin in defined ubiquitylation states in vitro. Chemical biology approaches are now used to link specific histone ubiquitylation marks with downstream chromatin regulation events on the molecular level. Here, we want to highlight how chemical biology approaches have empowered the mechanistic study of chromatin ubiquitylation in the context of gene regulation and DNA repair with attention to future challenges.

Abstract
Post-translational modifications (PTMs) endow proteins with new properties to respond to environmental changes or growth needs. With the development of advanced proteomics techniques, hundreds of distinct types of PTMs have been observed in a wide range of proteins from bacteria, archaea, and eukarya. To identify the roles of these PTMs, scientists have applied various approaches. However, high dynamics, low stoichiometry, and crosstalk between PTMs make it almost impossible to obtain homogeneously modified proteins for characterization of the site-specific effect of individual PTM on target proteins. To solve this problem, the genetic code expansion (GCE) strategy has been introduced into the field of PTM studies. Instead of modifying proteins after translation, GCE incorporates modified amino acids into proteins during translation, thus generating site-specifically modified proteins at target positions. In this review, we summarize the development of GCE systems for orthogonal translation for site-specific installation of PTMs.

Abstract
Liver cancer is ranked as the sixth most prevalent from of malignancy globally and stands as the third primary contributor to cancer-related mortality. Metastasis is the main reason for liver cancer treatment failure and patient deaths. Speckle-type POZ protein (SPOP) serves as a crucial substrate junction protein within the cullin-RING E3 ligase complex, acting as a significant tumor suppressor in liver cancer. Nevertheless, the precise molecular mechanism underlying the role of SPOP in liver cancer metastasis remain elusive. In the current study, we identified cAMP response element binding 5 (CREB5) as a novel SPOP substrate in liver cancer. SPOP facilitates non-degradative K63-polyubiquitination of CREB5 on K432 site, consequently hindering its capacity to activate receptor tyrosine kinase MET. Moreover, liver cancer-associated SPOP mutant S119N disrupts the SPOP-CREB5 interactions and impairs the ubiquitination of CREB5.This disruption ultimately leads to the activation of the MET signaling pathway and enhances metastatic properties of hepatoma cells both in vitro and in vivo. In conclusion, our findings highlight the functional significance of the SPOP-CREB5-MET axis in liver cancer metastasis.

Abstract
Ubiquitylation refers to the attachment of mono- or poly-ubiquitin molecules to a substrate protein. To shield ubiquitin chains against potential hydrolysis, a facile, click-chemistry based approach was recently established for the generation of site-specifically conjugated ubiquitin dimers relying on triazole-linkage. Here, the preparation of such ubiquitin chains was advanced by the generation of homotypic Lys11-linked ubiquitin trimers considering an isotopic labeling scheme in a moiety-wise manner. The structural and dynamical impact on the ubiquitin unit at proximal, central, or distal position that is potentially invoked by the respective other two moieties was systematically probed by heteronuclear high-resolution NMR spectroscopic approaches. As a result, conjugating a third ubiquitin moiety to the proximal or distal site of a ubiquitin dimer does not alter structural and dynamical characteristics as it has been seen for ubiquitin dimers. This observation suggests that recognition of a homotypically assembled ubiquitin chain by a potential substrate is primarily done by screening the length of a ubiquitin chain rather than relying on subtle changes in structure or dynamic properties of single ubiquitin moieties composing the chain.

Abstract
The conformational landscape of multi-domain proteins is inherently linked to their specific functions. This also holds for polyubiquitin chains that are assembled by two or more ubiquitin domains connected by a flexible linker thus showing a large interdomain mobility. However, molecular recognition and signal transduction are associated with particular conformational substates that are populated in solution. Here, we apply high-resolution NMR spectroscopy in combination with dual-scale MD simulations to explore the conformational space of K6-, K29-, and K33-linked diubiquitin molecules. The conformational ensembles are evaluated utilizing a paramagnetic cosolute reporting on solvent exposure plus a set of complementary NMR parameters. This approach unravels a conformational heterogeneity of diubiquitins and explains the diversity of structural models that have been determined for K6-, K29-, and K33-linked diubiquitins in free and ligand-bound states so far. We propose a general application of the approach developed here to demystify multi-domain proteins occurring in nature.

Abstract
The important roles played by branched polyubiquitin chains were recently uncovered in proteasomal protein degradation, mitotic regulation, and NF-κB signaling. With the new realization of a wide presence of branched ubiquitin chains in mammalian cells, there is an urgent need of identifying the reader and eraser proteins of the various branched ubiquitin chains. In this work, we report the generation of noncleavable branched triubiquitin probes with combinations of K11-, K48-, and K63-linkages. Through a pulldown approach using the branched triUb probes, we identified human proteins that recognize branched triubiquitin structures including ubiquitin-binding proteins and deubiquitinases (DUBs). Proteomics analysis of the identified proteins enriched by the branched triubiquitin probes points to possible roles of branched ubiquitin chains in cellular processes including DNA damage response, autophagy, and receptor endocytosis. In vitro characterization of several identified UIM-containing proteins demonstrated their binding to branch triubiquitin chains with moderate to high affinities. Availability of this new class of branched triubiquitin probes will enable future investigation into the roles of branched polyubiquitin chains through identification of specific reader and eraser proteins, and the modes of branched ubiquitin chain recognition and processing using biochemical and biophysical methods.

Abstract
Post-translational modifications (PTMs) of proteins not only exponentially increase the diversity of proteoforms, but also contribute to dynamically modulating the localization, stability, activity, and interaction of proteins. Understanding the biological consequences and functions of specific PTMs has been challenging for many reasons, including the dynamic nature of many PTMs and the technical limitations to access homogenously modified proteins. The genetic code expansion technology has emerged to provide unique approaches for studying PTMs. Through site-specific incorporation of unnatural amino acids (UAAs) bearing PTMs or their mimics into proteins, genetic code expansion allows the generation of homogenous proteins with site-specific modifications and atomic resolution both in vitro and in vivo. With this technology, various PTMs and mimics have been precisely introduced into proteins. In this review, we summarize the UAAs and approaches that have been recently developed to site-specifically install PTMs and their mimics into proteins for functional studies of PTMs.

Abstract
As one of the most prevalent protein post-translational modifications, ubiquitin modification plays a momentous role in regulating varied cellular functions. Different polyubiquitin linkage types have diverse effects on cell signaling. However, compared with short ubiquitin chains, the preparation of long ubiquitin chains remains difficult and expensive to purchase commercially. In this study, we constructed an enzyme library of ubiquitin-activating enzyme E1, ubiquitin-conjugating enzyme E2, and ubiquitin-ligase E3, which are specific for synthesizing K63, K48, and M1 linked polyubiquitin chains. We demonstrate that these distinctly linked polyubiquitin chains could be synthesized and purified with high yield and purity. More importantly, this method can synthesize longer ubiquitin chains, the longest can reach more than fifteen ubiquitin molecules, which provides great convenience for ubiquitin-related structural and functional studies.

Abstract
Engineering synthetic interfaces between membranes has potential applications in designing non-native cellular communication pathways and creating synthetic tissues. Here, InterSpy is introduced as a synthetic biology tool consisting of a heterodimeric protein engineered to form and maintain membrane-membrane interfaces between apposing synthetic as well as cell membranes through the SpyTag/SpyCatcher interaction. The inclusion of split fluorescent protein fragments in InterSpy allows tracking of the formation of a membrane-membrane interface and reconstitution of functional fluorescent protein in the space between apposing membranes. First, InterSpy is demonstrated by testing split protein designs using a mammalian cell-free expression (CFE) system. By utilizing co-translational helix insertion, cell-free synthesized InterSpy fragments are incorporated into the membrane of liposomes and supported lipid bilayers with the desired topology. Functional reconstitution of split fluorescent protein between the membranes is strictly dependent on SpyTag/SpyCatcher. Finally, InterSpy is demonstrated in mammalian cells by detecting fluorescence reconstitution of split protein at the membrane-membrane interface between two cells each expressing a component of InterSpy. InterSpy demonstrates the power of CFE systems in the functional reconstitution of synthetic membrane interfaces via proximity-inducing proteins. This technology may also prove useful where cell-cell contacts and communication are recreated in a controlled manner using minimal components.

Abstract
Development of (semi-)synthetic methods to prepare ubiquitin (Ub)-based reagents has proven to be helpful in the classification of deubiquitinating proteases (DUBs). To study DUB selectivity for one or more of the eight possible poly-Ub chains, fluorogenic assay reagents have been reported relying on the appearance of a fluorescent signal upon DUB-mediated cleavage of the reagent. In this protocol, we describe the use of such an assay to profile the selectivity of TRABID, a member of the OTU family of DUBs.

Abstract
Protein ubiquitination is a key post-translational modification in regulating many fundamental cellular processes and dysregulation of these processes can give rise to a vast array of diseases. Unravelling the molecular mechanisms of ubiquitination hence is an important area in current ubiquitin research with as aim to understand this enigmatic process. The complexity of ubiquitin (Ub) signaling arises from the large variety of Ub conjugates, where Ub is attached to other Ub proteins, Ub-like proteins, and protein substrates. The chemical preparation of such Ub conjugates in high homogeneity and in adequate amounts contributes greatly to the deciphering of Ub signaling. The strength of these chemically synthesized conjugates lies in the chemo-selectivity in which they can be created that are sometimes difficult to obtain using biochemical methodology. In this review, we will discuss the progress in the chemical protein synthesis of state-of-the-art Ub and Ub-like chemical probes, their unique concepts and related discoveries in the ubiquitin field.

Abstract
Ubiquitination is a critical type of protein post-translational modification playing an essential role in many cellular processes. To date, more than eight types of ubiquitination exist, all of which are involved in distinct cellular processes based on their structural differences. Studies have indicated that activation of the ubiquitination pathway is tightly connected with inflammation-related diseases as well as cancer, especially in the non-proteolytic canonical pathway, highlighting the vital roles of ubiquitination in metabolic programming. Studies relating degradable ubiquitination through lys48 or lys11-linked pathways to cellular signaling have been well-characterized. However, emerging evidence shows that non-degradable ubiquitination (linked to lys6, lys27, lys29, lys33, lys63, and Met1) remains to be defined. In this review, we summarize the non-proteolytic ubiquitination involved in tumorigenesis and related signaling pathways, with the aim of providing a reference for future exploration of ubiquitination and the potential targets for cancer therapies.

Abstract
Di-ubiquitin (diUB) conjugates of defined linkages are useful tools for probing the functions of UB ligases, UB-binding proteins and deubiquitinating enzymes (DUBs) in coding, decoding and editing the signals carried by the UB chains. Here we developed an efficient method for linkage-specific synthesis of diUB probes based on the incorporation of the unnatural amino acid (UAA) Nϵ -L-thiaprolyl-L-Lys (L-ThzK) into UB for ligation with another UB at a defined Lys position. The diUB formed by the UAA-mediated ligation reaction has a G76C mutation on the side of donor UB for conjugation with E2 and E3 enzymes or undergoing dethiolation to generate a covalent trap for DUBs. The development of UAA mutagenesis for diUB synthesis provides an easy route for preparing linkage-specific UB-based probes to decipher the biological signals mediated by protein ubiquitination.

Abstract
Protein post-translational modifications are involved in essentially all aspects of cellular signaling. Their dynamic nature and the difficulties in installing them using enzymatic approaches limits their direct study in human cells. Reported herein is the first synthesis, delivery and cellular study of a stable phosphoubiquitin probe. Our results compare Parkin's substrate preference during mitophagy via direct visualization of a phosphorylated ubiquitin probe in the cellular environment.

Abstract
The formation of protein complexes is central to biology, with oligomeric proteins more prevalent than monomers. The coupling of functionally and even structurally distinct protein units can lead to new functional properties not accessible by monomeric proteins alone. While such complexes are driven by evolutionally needs in biology, the ability to link normally functionally and structurally disparate proteins can lead to new emergent properties for use in synthetic biology and the nanosciences. Here we demonstrate how two disparate proteins, the haem binding helical bundle protein cytochrome b 562 and the β-barrel green fluorescent protein can be combined to form a heterodimer linked together by an unnatural triazole linkage. The complex was designed using computational docking approaches to predict compatible interfaces between the two proteins. Models of the complexes where then used to engineer residue coupling sites in each protein to link them together. Genetic code expansion was used to incorporate azide chemistry in cytochrome b 562 and alkyne chemistry in GFP so that a permanent triazole covalent linkage can be made between the two proteins. Two linkage sites with respect to GFP were sampled. Spectral analysis of the new heterodimer revealed that haem binding and fluorescent protein chromophore properties were retained. Functional coupling was confirmed through changes in GFP absorbance and fluorescence, with linkage site determining the extent of communication between the two proteins. We have thus shown here that is possible to design and build heterodimeric proteins that couple structurally and functionally disparate proteins to form a new complex with new functional properties.

Abstract
Decoding the role of histone posttranslational modifications (PTMs) is key to understand the fundamental process of epigenetic regulation. This is well studied for PTMs of core histones but not for linker histone H1 in general and its ubiquitylation in particular due to a lack of proper tools. Here, we report on the chemical synthesis of site-specifically mono-ubiquitylated H1.2 and identify its ubiquitin-dependent interactome on a proteome-wide scale. We show that site-specific ubiquitylation of H1 at position K64 modulates interactions with deubiquitylating enzymes and the deacetylase SIRT1. Moreover, it affects H1-dependent chromatosome assembly and phase separation resulting in a more open chromatosome conformation generally associated with a transcriptionally active chromatin state. In summary, we propose that site-specific ubiquitylation plays a general regulatory role for linker histone H1. While the role of specific posttranslational modifications (PTMs) is increasingly well understood for core histones, this is not the case for linker histone H1. Here the authors show that site-specific ubiquitylation of H1 results in distinct interactomes, regulates phase separation, and modulates assembly of chromatosomes.

Abstract
Ubiquitination is an important protein post-translational modification regulating many cellular processes in eukaryotes. Ubiquitination is catalyzed by a three-enzyme cascade resulting in the conjugation of the C-terminal carboxylate of ubiquitin (Ub) to the ε-amino group of a lysine residue in the acceptor protein via an isopeptide bond. In vitro enzymatic ubiquitination utilizing Ub ligases has been successfully employed to generate Ub dimers and polymers. However, limitations of the enzymatic approach exist, particularly due to the requirement of specific Ub ligase for any given target protein and the low catalytic efficiency of the Ub ligase. To achieve an in-depth understanding of the molecular mechanism of Ub signaling, new methods are needed to generate mono- and poly-ubiquitinated proteins at a specific site with defined polyubiquitin chain linkage and length. Chemical methods offer an attractive solution to the above-described challenges. In this review, we summarize the recently developed chemical methods for generating ubiquitinated proteins using synthetic and semisynthetic approaches. These new tools and approaches, as an important part of the Ub toolbox, are crucial to our understanding and exploitation of the Ub system for novel therapeutics.

Abstract
Protein ubiquitination regulates almost every process in eukaryotic cells. The study of the many enzymes involved in the ubiquitination system and the development of ubiquitination-associated therapeutics are important areas of current research. Synthetic tools such as ubiquitin-based chemical probes have been making an increasing contribution to deciphering various biochemical components involved in ubiquitin conjugation, recruitment, signaling, and deconjugation. In the present minireview, we summarize the progress of ubiquitin-based chemical probes with an emphasis on their various structures and chemical synthesis. We discuss the utility of the ubiquitin-based chemical probes for discovering and profiling ubiquitin-dependent signaling systems, as well as the monitoring and visualization of ubiquitin-related enzymatic machinery. We also show how the probes can serve to elucidate the molecular mechanism of recognition and catalysis. Collectively, the development and application of ubiquitin-based chemical probes emphasizes the importance and utility of chemical protein synthesis in modern chemical biology. This article reviews the design, synthesis, and application of different classes of Ub-based chemical probes.![]()

Abstract
Ubiquitin (UB) transfer cascades consisting of E1, E2, and E3 enzymes constitute a complex network that regulates a myriad of biologic processes by modifying protein substrates. Deubiquitinating enzymes (DUBs) reverse UB modifications or trim UB chains of diverse linkages. Additionally, many cellular proteins carry UB-binding domains (UBDs) that translate the signals encoded in UB chains to target proteins for degradation by proteasomes or in autophagosomes, as well as affect nonproteolytic outcomes such as kinase activation, DNA repair, and transcriptional regulation. Dysregulation of the UB transfer pathways and malfunctions of DUBs and UBDs play causative roles in the development of many diseases. A greater understanding of the mechanism of UB chain assembly and the signals encoded in UB chains should aid in our understanding of disease pathogenesis and guide the development of novel therapeutics. The recent flourish of protein-engineering approaches such as unnatural amino acid incorporation, protein semisynthesis by expressed protein ligation, and high throughput selection by phage and yeast cell surface display has generated designer proteins as powerful tools to interrogate cell signaling mediated by protein ubiquitination. In this study, we highlight recent achievements of protein engineering on mapping, probing, and manipulating UB transfer in the cell. SIGNIFICANCE STATEMENT: The post-translational modification of proteins with ubiquitin alters the fate and function of proteins in diverse ways. Protein engineering is fundamentally transforming research in this area, providing new mechanistic insights and allowing for the exploration of concepts that can potentially be applied to therapeutic intervention.

Abstract
Protein oligomers are more common in nature than monomers, with dimers being the most prevalent final structural state observed in known structures. From a biological perspective, this makes sense as it conserves vital molecular resources that may be wasted simply by generating larger single polypeptide units, and allows new features such as cooperativity to emerge. Taking inspiration from nature, protein designers and engineers are now building artificial oligomeric complexes using a variety of approaches to generate new and useful supramolecular protein structures. Oligomerisation is thus offering a new approach to sample structure and function space not accessible through simply tinkering with monomeric proteins.

Abstract
Ubiquitylation is an eminent posttranslational modification referring to the covalent attachment of single ubiquitin molecules or polyubiquitin chains to a target protein dictating the fate of such labeled polypeptide chains. Here, we have biochemically produced artificially Lys11-, and Lys27-, and Lys63-linked ubiquitin dimers based on click-chemistry generating milligram quantities in high purity. We show that the artificial linkage used for the conjugation of two ubiquitin moieties represents a fully reliable surrogate of the natural isopeptide bond by acquiring highly resolved nuclear magnetic resonance (NMR) spectroscopic data including ligand binding studies. Extensive coarse grained and atomistic molecular dynamics (MD) simulations allow to extract structures representing the ensemble of domain-domain conformations used to verify the experimental data. Advantageously, this methodology does not require individual isotopic labeling of both ubiquitin moieties as NMR data have been acquired on the isotopically labeled proximal moiety and complementary MD simulations have been used to fully interpret the experimental data in terms of domain-domain conformation. This combined approach intertwining NMR spectroscopy with MD simulations makes it possible to describe the conformational space non-canonically Lys11-, and Lys27-linked ubiquitin dimers occupy in a solution averaged ensemble by taking atomically resolved information representing all residues in ubiquitin dimers into account.

Abstract
Proteins controlling mineralization in vivo are diverse, suggesting that there are various ways by which mineralization can be directed in bioinspired approaches. While well-defined three-dimensional (3D) structures occur in biomineralization proteins, the design of synthetic, soluble, bioinspired macromolecules with specific, reproducible, and predictable 3D arrangements of mineral-interacting functions poses an ultimate challenge. Thus, the question of how certain arrangements of such functions on protein surfaces influence mineralization and in what ways specific alterations subsequently affect this process remains elusive. Here we used genetically engineered ubiquitin (Ub) proteins in order to overcome the limitations of generic bioinspired additive systems. By advancing existing protocols, we introduced an unnatural amino acid and subsequently mineral-interacting functions via selective-pressure incorporation and click chemistry, respectively, without affecting the Ub secondary structure. Indeed, as-obtained Ub with three phosphate functions at defined positions shows unique effects based on a yet-unmatched capability toward the stabilization of a film of a dense liquid mineral phase visible even with the naked eye and its transformation into amorphous nanoparticles and afterward crystals with complex shapes. We thereby demonstrate that Ub designer proteins pose a unique new generation of crystallization additives where the 3D arrangement of mineral-interacting functions can be designed at will, promising their future use for programmable, target-oriented mineralization control.

Abstract
As one of the most prevalent post-translational modifications in eukaryotic cells, ubiquitylation plays vital roles in many cellular processes, such as protein degradation, DNA metabolism, and cell differentiation. Substrate proteins can be tagged by distinct types of polymeric ubiquitin (Ub) chains, which determine the eventual fate of the modified protein. A facile, click chemistry based approach for the efficient generation of linkage-defined Ub chains, including Ub dimers, was recently established. Within these chains, individual Ub moieties are connected through a triazole linkage, rather than the natural isopeptide bond. Herein, it is reported that the conformation of an artificially K48-linked Ub dimer resembles that of the natively linked dimer, with respect to structural and dynamic characteristics, as demonstrated by means of high-resolution NMR spectroscopy. Thus, it is proposed that artificially linked Ub dimers, as generated by this approach, represent potent tools for studying the inherently different properties and functions of distinct Ub chains.

Abstract
Post-translational modification of proteins with ubiquitin and ubiquitin-like proteins (Ubls) is central to the regulation of eukaryotic cellular processes. Our ability to study the effects of ubiquitylation, however, is limited by the difficulty to prepare homogenously modified proteins in vitro and by the impossibility to selectively trigger specific ubiquitylation events in living cells. Here we combine genetic-code expansion, bioorthogonal Staudinger reduction and sortase-mediated transpeptidation to develop a general tool to ubiquitylate proteins in an inducible fashion. The generated ubiquitin conjugates display a native isopeptide bond and bear two point mutations in the ubiquitin C terminus that confer resistance toward deubiquitinases. Nevertheless, physiological integrity of sortase-generated diubiquitins in decoding cellular functions via recognition by ubiquitin-binding domains is retained. Our approach allows the site-specific attachment of Ubls to nonrefoldable, multidomain proteins and enables inducible and ubiquitin-ligase-independent ubiquitylation of proteins in mammalian cells, providing a powerful tool to dissect the biological functions of ubiquitylation with temporal control.

Abstract
Ubiquitin-binding proteins play an important role in eukaryotes by translating differently linked polyubiquitin chains into proper cellular responses. Current knowledge about ubiquitin-binding proteins and ubiquitin linkage-selective interactions is mostly based on case-by-case studies. We have recently reported a method called ubiquitin interactor affinity enrichment-mass spectrometry (UbIA-MS), which enables comprehensive identification of ubiquitin interactors for all ubiquitin linkages from crude cell lysates. One major strength of UbIA-MS is the fact that ubiquitin interactors are enriched from crude cell lysates, in which proteins are present at endogenous levels, contain biologically relevant post-translational modifications (PTMs) and are assembled in native protein complexes. In addition, UbIA-MS uses chemically synthesized nonhydrolyzable diubiquitin, which mimics native diubiquitin and is inert to cleavage by endogenous deubiquitinases (DUBs). Here, we present a detailed protocol for UbIA-MS that proceeds in five stages: (i) chemical synthesis of ubiquitin precursors and click chemistry for the generation of biotinylated nonhydrolyzable diubiquitin baits, (ii) in vitro affinity purification of ubiquitin interactors, (iii) on-bead interactor digestion, (iv) liquid chromatography (LC)-MS/MS analysis and (v) data analysis to identify differentially enriched proteins. The computational analysis tools are freely available as an open-source R software package, including a graphical interface. Typically, UbIA-MS allows the identification of dozens to hundreds of ubiquitin interactors from any type of cell lysate, and can be used to study cell type or stimulus-dependent ubiquitin interactions. The nonhydrolyzable diubiquitin synthesis can be completed in 3 weeks, followed by ubiquitin interactor enrichment and identification, which can be completed within another 2 weeks.

Abstract
Emerging strategies targeting site-specific protein modifications allow for unprecedented selectivity, fast kinetics and mild reaction conditions with high yield. These advances open exciting novel possibilities for the effective bioorthogonal decoration of biomaterials with therapeutic proteins. Site-specificity is particularly important to the therapeutics' end and translated by targeting specific functional groups or introducing new functional groups into the therapeutic at predefined positions. Biomimetic strategies are designed for modification of therapeutics emulating enzymatic strategies found in Nature. These strategies are suitable for a diverse range of applications - not only for protein-polymer conjugation, particle decoration and surface immobilization, but also for the decoration of complex biomaterials and the synthesis of bioresponsive drug delivery systems. This article reviews latest chemical and enzymatic strategies for the biorthogonal decoration of biomaterials with therapeutic proteins and inter-positioned linker structures. Finally, the numerous reports at the interface of biomaterials, linkers, and therapeutic protein decoration are integrated into practical advice for design considerations intended to support the selection of productive ligation strategies.

Abstract
Ubiquitination is a key posttranslational modification, which affects numerous biological processes and is reversed by a class of enzymes known as deubiquitinases (DUBs). This family of enzymes cleaves mono-ubiquitin or poly-ubiquitin chains from a target protein through different mechanisms and mode of interactions with their substrates. Studying the role of DUBs in health and diseases has been a major goal for many laboratories both in academia and in industry. However, the field has been challenged by the difficulties in obtaining native substrates and novel reagents using traditional enzymatic and molecular biology approaches. Recent advancements in the synthesis and semisynthesis of proteins made it possible to prepare several unique ubiquitin conjugates to study various aspects of DUBs such as their specificities and structures. Moreover, these approaches enable the preparation of novel activity based probes and assays to monitor DUB activities in vitro and in cellular contexts. Efforts made to bring new chemical entities for the selective inhibition of DUBs based on these tools are also highlighted with selected examples.

Abstract
Most intracellular proteins are subjected to post-translational modification by ubiquitin. Accordingly, it is of fundamental importance to investigate the biological and physicochemical effects of ubiquitylation on substrate proteins. However, preparation of ubiquitylated proteins by an enzymatic synthesis bears limitations in terms of yield and site-specificity. Recently established chemical ubiquitylation methodologies can overcome these problems and provide a new understanding of ubiquitylation. Herein we describe the recent chemical ubiquitylation procedures with a focus on the effects of ubiquitylation on target proteins revealed by the synthetic approach.

Abstract
The modification of proteins with ubiquitin (Ub) is an important regulator of eukaryotic biology and deleterious perturbation of this process is widely linked to the onset of various diseases. The regulatory capacity of the Ub signal is high and, in part, arises from the capability of Ub to be enzymatically polymerised to form polyubiquitin (polyUb) chains of eight different linkage types. These distinct polyUb topologies can then be site-specifically conjugated to substrate proteins to elicit a number of cellular outcomes. Therefore, to further elucidate the biological significance of substrate ubiquitination, methodologies that allow the production of defined polyUb species, and substrate proteins that are site-specifically modified with them, are essential to progress our understanding. Many chemically inspired methods have recently emerged which fulfil many of the criteria necessary for achieving deeper insight into Ub biology. With a view to providing immediate impact in traditional biology research labs, the aim of this review is to provide an overview of the techniques that are available for preparing Ub conjugates and polyUb chains with focus on approaches that use recombinant protein building blocks. These approaches either produce a native isopeptide, or analogue thereof, that can be hydrolysable or non-hydrolysable by deubiquitinases. The most significant biological insights that have already been garnered using such approaches will also be summarized.

Abstract
Posttranslational modification of proteins by ubiquitin (Ub), i.e., ubiquitination, mediates a variety of cellular processes, including protein homeostasis, cell cycle, DNA repair, and viral infections. Understanding the molecular mechanism of ubiquitination in these events is the basis for unraveling its precise role in health and disease. However, the inherent complexity of Ub signaling due to the high atomic complexity of Ub conjugates, where Ub is attached to other Ub molecules and to protein substrates in various forms, imposes a major challenge for these studies. In this regard, the enzymatic approaches employed for the preparation of important Ub conjugates have severe limitations to deliver them in high homogeneity and in adequate amounts for the desired study. Recent developments in the area of chemical synthesis and semisynthesis of proteins offer great solutions to the enzymatic limitations and enabling the preparation of various Ub conjugates with precise control over the atomic structure. These conjugates significantly contribute to deciphering Ub signaling at the molecular level, and with the synthetic tools in hand, chemical biologists have become key players in efforts toward understanding the complexity of the Ub code. In this Perspective, we highlight the key contributions of these synthetic approaches and how the development of novel Ub-based reagents is greatly assisting in uncovering unknown aspects of Ub signaling. We also discuss future aspirations to address unresolved questions in this exciting area of research.

Abstract
Intracellular signaling via the covalent attachment of different ubiquitin linkages to protein substrates is fundamental to many cellular processes. Although linkage-selective ubiquitin interactors have been studied on a case-by-case basis, proteome-wide analyses have not been conducted yet. Here, we present ubiquitin interactor affinity enrichment-mass spectrometry (UbIA-MS), a quantitative interaction proteomics method that makes use of chemically synthesized diubiquitin to enrich and identify ubiquitin linkage interactors from crude cell lysates. UbIA-MS reveals linkage-selective diubiquitin interactions in multiple cell types. For example, we identify TAB2 and TAB3 as novel K6 diubiquitin interactors and characterize UCHL3 as a K27-linkage selective interactor that regulates K27 polyubiquitin chain formation in cells. Additionally, we show a class of monoubiquitin and K6 diubiquitin interactors whose binding is induced by DNA damage. We expect that our proteome-wide diubiquitin interaction landscape and established workflows will have broad applications in the ongoing efforts to decipher the complex language of ubiquitin signaling.

Abstract
BACKGROUND Genetic code expansion has developed into an elegant tool to incorporate unnatural amino acids (uAA) at predefined sites in the protein backbone in response to an amber codon. However, recombinant production and yield of uAA comprising proteins are challenged due to the additional translation machinery required for uAA incorporation. RESULTS We developed a microtiter plate-based high-throughput monitoring system (HTMS) to study and optimize uAA integration in the model protein enhanced green fluorescence protein (eGFP). Two uAA, propargyl-L-lysine (Plk) and (S)-2-amino-6-((2-azidoethoxy) carbonylamino) hexanoic acid (Alk), were incorporated at the same site into eGFP co-expressing the native PylRS/tRNAPylCUA pair originating from Methanosarcina barkeri in E. coli. The site-specific uAA functionalization was confirmed by LC-MS/MS analysis. uAA-eGFP production and biomass growth in parallelized E. coli cultivations was correlated to (i) uAA concentration and the (ii) time of uAA addition to the expression medium as well as to induction parameters including the (iii) time and (iv) amount of IPTG supplementation. The online measurements of the HTMS were consolidated by end point-detection using standard enzyme-linked immunosorbent procedures. CONCLUSION The developed HTMS is powerful tool for parallelized and rapid screening. In light of uAA integration, future applications may include parallelized screening of different PylRS/tRNAPylCUA pairs as well as further optimization of culture conditions.

Abstract
Information embedded in different ubiquitin chains is transduced by proteins with ubiquitin-binding domains (UBDs) and erased by a set of hydrolytic enzymes referred to as deubiquitinases (DUBs). Understanding the selectivity of UBDs and DUBs is necessary for decoding the functions of different ubiquitin chains. Critical to these efforts is the access to chemically defined ubiquitin chains bearing site-specific fluorescent labels. One approach toward constructing such molecules involves peptide ligation by sortase (SrtA), a bacterial transpeptidase responsible for covalently attaching cell surface proteins to the cell wall. Here, we demonstrate the utility of SrtA in modifying individual subunits of ubiquitin chains. Using ubiquitin derivatives in which an N-terminal glycine is unveiled after protease-mediated digestion, we synthesized ubiquitin dimers, trimers, and tetramers with different isopeptide linkages. SrtA was then used in combination with fluorescent depsipeptide substrates to effect the modification of each subunit in a chain. By constructing branched ubiquitin chains with individual subunits tagged with a fluorophore, we provide evidence that the ubiquitin-specific protease USP15 prefers ubiquitin trimers but has little preference for a particular isopeptide linkage. Our results emphasize the importance of subunit-specific labeling of ubiquitin chains when studying how DUBs process these chains.

Abstract
We describe the genetically directed incorporation of aminooxy functionality into recombinant proteins by using a mutant Methanosarcina barkeri pyrrolysyl‐tRNA synthetase/tRNACUA pair. This allows the general production of nonhydrolysable ubiquitin conjugates of recombinant origin by bioorthogonal oxime ligation. This was exemplified by the preparation of nonhydrolysable versions of diubiquitin, polymeric ubiquitin chains and ubiquitylated SUMO. The conjugates exhibited unrivalled isostery with the native isopeptide bond, as inferred from structural and biophysical characterisation. Furthermore, the conjugates functioned as nanomolar inhibitors of deubiquitylating enzymes and were recognised by linkage‐specific antibodies. This technology should provide a versatile platform for the development of powerful tools for studying deubiquitylating enzymes and for elucidating the cellular roles of diverse polyubiquitin linkages.

Abstract
Ubiquitin (Ub) is a small post-translational modifier protein involved in a myriad of biochemical processes including DNA damage repair, proteasomal proteolysis, and cell cycle control. Ubiquitin signaling pathways have not been completely deciphered due to the complex nature of the enzymes involved in ubiquitin conjugation and deconjugation. Hence, probes and assay reagents are important to get a better understanding of this pathway. Recently, improvements have been made in synthesis procedures of Ub derivatives. In this perspective, we explain various research reagents available and how chemical synthesis has made an important contribution to Ub research.

Abstract
The reversible modification of protein by the small protein ubiquitin and other ubiquitin-like modifiers plays important roles in virtually every key biological process in eukaryotic cells. The establishment of a range of chemical methods for the preparation of ubiquitinated proteins has enabled the site-specific interrogation of the consequences of these modifications. However, many of these techniques require significant levels of synthetic expertise, somewhat limiting their widespread application by the biological community. To overcome this issue, the creation of structural analogues of the ubiquitin-protein linkage that can be readily prepared with commercially available reagents and buffers is an important goal. Here we present the development of conditions for the facile synthesis of bis-thio-acetone (BTA) linkages of ubiquitinated proteins in high yields. Additionally, we apply this technique to the preparation of the aggregation prone protein α-synuclein bearing either ubiquitin or the small ubiquitin-like modifier (SUMO). With these proteins, we demonstrate that the BTA linkage recapitulates the previously published effects of either of these proteins on α-synuclein, suggesting that it is a good structural mimic. Notably, the BTA linkage is chemically and enzymatically stable, enabling us to study the consequences of site-specific ubiquitination and SUMOylation on the toxicity of α-synuclein in cell culture, which revealed modification and site-specific differences.
