Abstract
Over 500 natural and synthetic amino acids have been genetically encoded in the last two decades. Incorporating these noncanonical amino acids into proteins enables many powerful applications, ranging from basic research to biotechnology, materials science, and medicine. However, major challenges remain to unleash the full potential of genetic code expansion across disciplines. Here, we provide an overview of diverse genetic code expansion methodologies and systems and their final applications in prokaryotes and eukaryotes, represented by Escherichia coli and mammalian cells as the main workhorse model systems. We highlight the power of how new technologies can be first established in simple and then transferred to more complex systems. For example, whole-genome engineering provides an excellent platform in bacteria for enabling transcript-specific genetic code expansion without off-targets in the transcriptome. In contrast, the complexity of a eukaryotic cell poses challenges that require entirely new approaches, such as striving toward establishing novel base pairs or generating orthogonally translating organelles within living cells. We connect the milestones in expanding the genetic code of living cells for encoding novel chemical functionalities to the most recent scientific discoveries, from optimizing the physicochemical properties of noncanonical amino acids to the technological advancements for their in vivo incorporation. This journey offers a glimpse into the promising developments in the years to come.

Abstract
Over the past 16 years, genetic code expansion and reprogramming in living organisms has been transformed by advances that leverage the unique properties of pyrrolysyl-tRNA synthetase (PylRS)/tRNAPyl pairs. Here we summarize the discovery of the pyrrolysine system and describe the unique properties of PylRS/tRNAPyl pairs that provide a foundation for their transformational role in genetic code expansion and reprogramming. We describe the development of genetic code expansion, from E. coli to all domains of life, using PylRS/tRNAPyl pairs, and the development of systems that biosynthesize and incorporate ncAAs using pyl systems. We review applications that have been uniquely enabled by the development of PylRS/tRNAPyl pairs for incorporating new noncanonical amino acids (ncAAs), and strategies for engineering PylRS/tRNAPyl pairs to add noncanonical monomers, beyond α-L-amino acids, to the genetic code of living organisms. We review rapid progress in the discovery and scalable generation of mutually orthogonal PylRS/tRNAPyl pairs that can be directed to incorporate diverse ncAAs in response to diverse codons, and we review strategies for incorporating multiple distinct ncAAs into proteins using mutually orthogonal PylRS/tRNAPyl pairs. Finally, we review recent advances in the encoded cellular synthesis of noncanonical polymers and macrocycles and discuss future developments for PylRS/tRNAPyl pairs.

Abstract
In recent years, powerful genetic code reprogramming methods have emerged that allow new functional components to be embedded into proteins as noncanonical amino acid (ncAA) side chains. In this review, we will illustrate how the availability of an expanded set of amino acid building blocks has opened a wealth of new opportunities in enzymology and biocatalysis research. Genetic code reprogramming has provided new insights into enzyme mechanisms by allowing introduction of new spectroscopic probes and the targeted replacement of individual atoms or functional groups. NcAAs have also been used to develop engineered biocatalysts with improved activity, selectivity, and stability, as well as enzymes with artificial regulatory elements that are responsive to external stimuli. Perhaps most ambitiously, the combination of genetic code reprogramming and laboratory evolution has given rise to new classes of enzymes that use ncAAs as key catalytic elements. With the framework for developing ncAA-containing biocatalysts now firmly established, we are optimistic that genetic code reprogramming will become a progressively more powerful tool in the armory of enzyme designers and engineers in the coming years.

Abstract
Histone lysine acetylation (Kac) and crotonylation (Kcr) marks mediate the recruitment of YEATS domains to chromatin. In this way, YEATS domain-containing proteins such as AF9 participate in the regulation of DNA-templated processes. Our previous study showed that the replacement of Kac/Kcr by a 2-furancarbonyllysine (Kfu) residue led to greatly enhanced affinity toward the AF9 YEATS domain, rendering Kfu-containing peptides useful chemical tools to probe the AF9 YEATS-Kac/Kcr interactions. Here, we report the genetic incorporation of Kfu in Escherichia coli and mammalian cells through the amber codon suppression technology. We develop a Kfu-containing epitope tag, termed RAY-tag, which can robustly and selectively engage with the AF9 YEATS domain in vitro and in cellulo. We further demonstrate that the fusion of RAY-tag to different protein modules, including fluorescent proteins and DNA binding proteins, can facilitate the interrogation of the histone lysine acylation-mediated recruitment of the AF9 YEATS domain in different biological contexts.

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
The ability to genetically encode noncanonical amino acids (ncAAs) has empowered proteins with improved or previously unknown properties. However, existing strategies in mammalian cells rely on the introduction of a blank codon to incorporate ncAAs, which is inefficient and limits their widespread applications. In this study, we developed a rare codon recoding strategy that takes advantage of the relative rarity of the TCG codon to achieve highly selective and efficient ncAA incorporation through systematic engineering and big data-model predictions. We highlight the broad utility of this strategy for the incorporation of dozens of ncAAs into various functional proteins at the wild-type protein expression levels, as well as the synthesis of proteins with up to six-site ncAAs or four distinct ncAAs in mammalian cells for downstream applications.

Leveraging a Phage-Encoded Noncanonical Amino Acid: A Novel Pathway to Potent and Selective Epigenetic Reader Protein Inhibitors. ACS CENTRAL SCIENCE 2024; 10:782-792.

Abstract
Epigenetic reader proteins interpret histone epigenetic marks to regulate gene expression. Given their vital roles and the link between their dysfunction and various diseases, these proteins present compelling targets for therapeutic interventions. Nevertheless, designing selective inhibitors for these proteins poses significant challenges, primarily due to their unique properties such as shallow binding sites and similarities with homologous proteins. To overcome these challenges, we propose an innovative strategy that uses phage display with a genetically encoded noncanonical amino acid (ncAA) containing an epigenetic mark. This ncAA guides binding to the reader protein's active site, allowing the identification of peptide inhibitors with enhanced affinity and selectivity. In this study, we demonstrate this novel approach's effectiveness by identifying potent inhibitors for the ENL YEATS domain that plays a critical role in leukemogenesis. Our strategy involved genetically incorporating Nε-butyryl-l-lysine (BuK), known for its binding to ENL YEATS, into a phage display library for enriching the pool of potent inhibitors. One resultant hit was further optimized by substituting BuK with other pharmacophores to exploit a unique π-π-π stacking interaction with ENL YEATS. This led to the creation of selective ENL YEATS inhibitors with a KD value of 2.0 nM and a selectivity 28 times higher for ENL YEATS than its close homologue AF9 YEATS. One such inhibitor, tENL-S1f, demonstrated robust cellular target engagement and on-target effects to inhibit leukemia cell growth and suppress the expression of ENL target genes. As a pioneering study, this work opens up extensive avenues for the development of potent and selective peptidyl inhibitors for a broad spectrum of epigenetic reader proteins.

Abstract
Genetic and genomic techniques have proven incredibly powerful for identifying and studying molecular players implicated in the epigenetic regulation of DNA-templated processes such as transcription. However, achieving a mechanistic understanding of how these molecules interact with chromatin to elicit a functional output is non-trivial, owing to the tremendous complexity of the biochemical networks involved. Advances in protein engineering have enabled the reconstitution of 'designer' chromatin containing customized post-translational modification patterns, which, when used in conjunction with sophisticated biochemical and biophysical methods, allow many mechanistic questions to be addressed. In this Review, we discuss how such tools complement established 'omics' techniques to answer fundamental questions on chromatin regulation, focusing on chromatin mark establishment and protein-chromatin interactions.

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
The role of histone post-translational modifications (PTMs) in chromatin structure and genome function has been the subject of intense debate for more than 60 years. Though complex, the discourse can be summarized in two distinct - and deceptively simple - questions: What is the function of histone PTMs? And how should they be studied? Decades of research show these queries are intricately linked and far from straightforward. Here we provide a historical perspective, highlighting how the arrival of new technologies shaped discovery and insight. Despite their limitations, the tools available at each period had a profound impact on chromatin research, and provided essential clues that advanced our understanding of histone PTM function. Finally, we discuss recent advances in the application of defined nucleosome substrates, the study of multivalent chromatin interactions, and new technologies driving the next era of histone PTM research.

Abstract
Histones are proteins which help to organize DNA. The way in which they function is complex and is partially controlled by post-translational modifications (PTMs). Histone proteins from numerous organisms can be recombinantly produced in bacteria, but many bacterial strains are incapable of installing the variety of PTMs that histones possess. An alternative method of producing histones, which can be used to introduce PTMs, is native chemical ligation (NCL). This chapter provides a general NCL protocol which can be used to produce synthetic, post-translationally modified, histone proteins. The focus is on the NCL procedure itself and not on producing the modified histone protein fragments as there are many different ways in which these can be synthesized, depending on the modification(s) required. The same NCL protocol is also applicable for expressed protein ligation (EPL) with only small modifications to the purification procedure potentially required.

Abstract
Histone lysine acylation, including acetylation and crotonylation, plays a pivotal role in gene transcription in health and diseases. However, our understanding of histone lysine acylation has been limited to gene transcriptional activation. Here, we report that histone H3 lysine 27 crotonylation (H3K27cr) directs gene transcriptional repression rather than activation. Specifically, H3K27cr in chromatin is selectively recognized by the YEATS domain of GAS41 in complex with SIN3A-HDAC1 co-repressors. Proto-oncogenic transcription factor MYC recruits GAS41/SIN3A-HDAC1 complex to repress genes in chromatin, including cell-cycle inhibitor p21. GAS41 knockout or H3K27cr-binding depletion results in p21 de-repression, cell-cycle arrest, and tumor growth inhibition in mice, explaining a causal relationship between GAS41 and MYC gene amplification and p21 downregulation in colorectal cancer. Our study suggests that H3K27 crotonylation signifies a previously unrecognized, distinct chromatin state for gene transcriptional repression in contrast to H3K27 trimethylation for transcriptional silencing and H3K27 acetylation for transcriptional activation.

Abstract
Protein posttranslational modifications (PTMs) play critical roles in regulating cellular activities. Here we provide a survey of genetic code expansion (GCE) methods that were applied in the co-translational installation and studies of PTMs through noncanonical amino acid (ncAA) mutagenesis. We begin by reviewing types of PTM that have been installed by GCE with a focus on modifications of tyrosine, serine, threonine, lysine, and arginine residues. We also discuss examples of applying these methods in biological studies. Finally, we end the piece with a short discussion on the challenges and the opportunities of the field.

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
Posttranslational modifications (PTMs) of lysine residues are major regulators of gene expression, protein-protein interactions, and protein localization and degradation. Histone lysine benzoylation is a recently identified epigenetic marker associated with active transcription, which has physiological relevance distinct from histone acetylation and can be regulated by debenzoylation of sirtuin 2 (SIRT2). Herein, we provide a protocol for the incorporation of benzoyllysine and fluorinated benzoyllysine into full-length histone proteins, which further serve as benzoylated histone probes with NMR or fluorescence signal for investigating the dynamics of SIRT2-mediated debenzoylation.

Abstract
Post-translational modifications (PTMs) occurring on lysine residues, especially diverse forms of acylations, have seen rapid growth over the past two decades. Among them, lactylation and β-hydroxybutyrylation of lysine side-chains are newly identified histone marks and their implications in physiology and diseases have aroused broad research interest. Meanwhile, lysine lipoylation is highly conserved in diverse organisms and well known for the pivotal role in central metabolic pathways, and recent findings in the proteomic profiling of protein lipoylation have nonetheless suggested a pressing need for an extensive investigation. For both basic and applied research, it is highly necessary to prepare PTM-bearing proteins particularly in a site-specific manner. Herein, we use genetic code expansion to site-specifically generate these lysine PTMs, including lactylation, β-hydroxybutyrylation and lipoylation in proteins in E. coli and mammalian cells. Notably using strategies including activity-based selection, screening and rational design, unique pyrrolysyl-tRNA synthetase variants were successfully evolved for each of the three non-canonical amino acids and enable efficient production of recombinant proteins, thus holding promise to benefit relevant studies. Through encoding these ncAAs, we examined the deacylase activities of mammalian sirtuins to these modifications, and importantly unfold lipoamidase activity of several sirtuins.

Abstract
Deciphering the endogenous interactors of histone post-translational modifications (hPTMs, also called histone marks) is essential to understand the mechanisms of epigenetic regulation. However, most of the analytical methods to determine hPTM interactomes are in vitro settings, lacking interrogating native chromatin. Although lysine crotonylation (Kcr) has recently been considered an important hPTM for the regulation of gene transcription, the interactors of Kcr still remain to be explored. Herein, we present a general approach relying upon a genetic code expansion system, APEX2 (engineered peroxidase)-mediated proximity labeling, and quantitative proteomics to profile interactomes of the selected hPTMs in living cells. We genetically fused APEX2 to the recombinant histone H3 with a crotonyl lysine inserted site specifically to generate APEX2-H3K9cr that incorporated into native chromatin. Upon activation, APEX2 triggered in vivo biotin labeling of H3K9cr interactors that can then be enriched with streptavidin beads and identified by mass spectrometry. Proteomic analysis further revealed the endogenous interactomes of H3K9cr and confirmed the reliability of the method. Moreover, DPF2 was identified as a candidate interactor, and the binding interaction of DPF2 to H3K9c was further characterized and verified. This study provides a novel strategy for the identification of hPTM interactomes in living cells, and we envision that this is key to elucidating epigenetic regulatory pathways.

Elucidation of binding preferences of YEATS domains to site-specific acetylated nucleosome core particles. J Biol Chem 2022; 298:102164.

Abstract
Acetylated lysine residues (Kac) in histones are recognized by epigenetic reader proteins, such as Yaf9, ENL, AF9, Taf14, and Sas5 (YEATS) domain-containing proteins. Human YEATS domains bind to the acetylated N-terminal tail of histone H3; however, their Kac-binding preferences at the level of the nucleosome are unknown. Through genetic code reprogramming, here, we established a nucleosome core particle (NCP) array containing histones that were acetylated at specific residues and used it to compare the Kac-binding preferences of human YEATS domains. We found that AF9-YEATS showed basal binding to the unmodified NCP and that it bound stronger to the NCP containing a single acetylation at one of K4, K9, K14, or K27 of H3, or to histone H4 multi-acetylated between K5 and K16. Crystal structures of AF9-YEATS in complex with an H4 peptide diacetylated either at K5/K8 or K8/K12 revealed that the aromatic cage of the YEATS domain recognized the acetylated K8 residue. Interestingly, E57 and D103 of AF9, both located outside of the aromatic cage, were shown to interact with acetylated K5 and K12 of H4, respectively, consistent with the increase in AF9-YEATS binding to the H4K8-acetylated NCP upon additional acetylation at K5 or K12. Finally, we show that a mutation of E57 to alanine in AF9-YEATS reduced the binding affinity for H4 multiacetylated NCPs containing H4K5ac. Our data suggest that the Kac-binding affinity of AF9-YEATS increases additively with the number of Kac in the histone tail.

Abstract
In living systems, the chemical space and functional repertoire of proteins are dramatically expanded through the post-translational modification (PTM) of various amino acid residues. These modifications frequently trigger unique protein-protein interactions (PPIs) - for example with reader proteins that directly bind the modified amino acid residue - which leads to downstream functional outcomes. The modification of a protein can also perturb its PPI network indirectly, for example, through altering its conformation or subcellular localization. Uncovering the network of unique PTM-triggered PPIs is essential to fully understand the roles of an ever-expanding list of PTMs in our biology. In this review, we discuss established strategies and current challenges associated with this endeavor.

Abstract
The evolutional development of the RNA translation process that leads to protein synthesis based on naturally occurring amino acids has its continuation via synthetic biology, the so-called rational bioengineering. Genetic code expansion (GCE) explores beyond the natural translational processes to further enhance the structural properties and augment the functionality of a wide range of proteins. Prokaryotic and eukaryotic ribosomal machinery have been proven to accept engineered tRNAs from orthogonal organisms to efficiently incorporate noncanonical amino acids (ncAAs) with rationally designed side chains. These side chains can be reactive or functional groups, which can be extensively utilized in biochemical, biophysical, and cellular studies. Genetic code extension offers the contingency of introducing more than one ncAA into protein through frameshift suppression, multi-site-specific incorporation of ncAAs, thereby increasing the vast number of possible applications. However, different mediating factors reduce the yield and efficiency of ncAA incorporation into synthetic proteins. In this review, we comment on the recent advancements in genetic code expansion to signify the relevance of systems biology in improving ncAA incorporation efficiency. We discuss the emerging impact of tRNA modifications and metabolism in protein design. We also provide examples of the latest successful accomplishments in synthetic protein therapeutics and show how codon expansion has been employed in various scientific and biotechnological applications.

Abstract
Various post-translational modifications can naturally occur on proteins, regulating the activity, subcellular localization, interaction, or stability of the proteins. However, it can be challenging to decipher the biological implication or physiological roles of site-specific modifications due to their dynamic and sub-stoichiometric nature. Genetic code expansion method, relying on an orthogonal aminoacyl-tRNA synthetase/tRNA pair, enables site-specific incorporation of non-canonical amino acids. Here we focus on the application of genetic code expansion to study site-specific protein post-translational modification in vitro and in vivo. After a brief introduction, we discuss possibilities of incorporating non-canonical amino acids containing post-translational modifications or their mimics into target proteins. This approach is applicable for Ser/Thr/Tyr phosphorylation, Tyr sulfation and nitration, Lys acetylation and acylation, Lys/His mono-methylation, as well as Arg citrullination. The next section describes the use of a precursor non-canonical amino acid followed by chemical and/or enzymatic reactions to afford the desired modification, such as Cys/Lys acylation, ubiquitin and ubiquitin-like modifications, as well as Lys/Gln methylation. We also discuss means for functional regulation of enzymes involving in post-translational modifications through genetically incorporated non-canonical amino acids. Lastly, the limitations and perspectives of genetic code expansion in studying protein post-translational modification are described.

Dynamic crotonylation of EB1 by TIP60 ensures accurate spindle positioning in mitosis. Nat Chem Biol 2021; 17:1314-1323.

Abstract
Spindle position control is essential for cell fate determination and organogenesis. Early studies indicate the essential role of the evolutionarily conserved Gαi/LGN/NuMA network in spindle positioning. However, the regulatory mechanisms that couple astral microtubules dynamics to the spindle orientation remain elusive. Here we delineated a new mitosis-specific crotonylation-regulated astral microtubule-EB1-NuMA interaction in mitosis. EB1 is a substrate of TIP60, and TIP60-dependent crotonylation of EB1 tunes accurate spindle positioning in mitosis. Mechanistically, TIP60 crotonylation of EB1 at Lys66 forms a dynamic link between accurate attachment of astral microtubules to the lateral cell cortex defined by NuMA-LGN and fine tune of spindle positioning. Real-time imaging of chromosome movements in HeLa cells expressing genetically encoded crotonylated EB1 revealed the importance of crotonylation dynamics for accurate control of spindle orientation during metaphase-anaphase transition. These findings delineate a general signaling cascade that integrates protein crotonylation with accurate spindle positioning for chromosome stability in mitosis.

Abstract
Histone posttranslational modifications (PTMs) are vital epigenetic regulators in many fundamental cell signaling pathways and diverse biological processes. Histone lysine benzoylation is a recently identified epigenetic mark associated with active transcription; however, it remains to be explored. Herein, we first report the genetic encoding of benzoyllysine and fluorinated benzoyllysines into full-length histone proteins in a site-specific manner in live cells, based on our rationally designed synthetase and fine-integrated fluorine element into benzoyllysines. The incorporated unnatural amino acids integrating unique features were demonstrated as versatile probes for investigating histone benzoylation under biological environments, conferring multiplex signals such as 19F NMR spectra with chemical clarity and fluorescence signals for benzoylation. Moreover, the site specifically incorporated lysine benzoylation within native full-length histone proteins revealed distinct dynamics of debenzoylation in the presence of debenzoylase sirtuin 2 (SIRT2). Our developed strategy for genetic encoding of benzoyllysines offers a general and novel approach to gain insights into interactions of site-specific histone benzoylation modifications with interactomes and molecular mechanisms in physiological settings, which could not be accessible with fragment histone peptides. This versatile chemical tool enables a direct and new avenue to explore benzoylation, interactions, and histone epigenetics, which will provide broad utilities in chemical biology, protein science, and basic biology research.

Abstract
Lysine acylation is a ubiquitous protein modification that controls various aspects of protein function, such as the activity, localization, and stability of enzymes. Mass spectrometric identification of lysine acylations has witnessed tremendous improvements in sensitivity over the last decade, facilitating the discovery of thousands of lysine acylation sites in proteins involved in all essential cellular functions across organisms of all domains of life. However, the vast majority of currently known acylation sites are of unknown function. Semi-synthetic methods for installing lysine derivatives are ideally suited for in vitro experiments, while genetic code expansion (GCE) allows the installation and study of such lysine modifications, especially their dynamic properties, in vivo. An overview of the current state of the art is provided, and its potential is illustrated with case studies from recent literature. These include the application of engineered enzymes and GCE to install lysine modifications or photoactivatable crosslinker amino acids. Their use in the context of central metabolism, bacterial and viral pathogenicity, the cytoskeleton and chromatin dynamics, is investigated.

Abstract
Genetic code expansion with unnatural amino acids (UAAs) has significantly broadened the chemical repertoire of proteins. Applications of this method in mammalian cells include probing of molecular interactions, conditional control of biological processes, and new strategies for therapeutics and vaccines. A number of methods have been developed for transient UAA mutagenesis in mammalian cells, each with unique features and advantages. All have in common a need to deliver genes encoding additional protein biosynthetic machinery (an orthogonal tRNA/tRNA synthetase pair) and a gene for the protein of interest. In this study, we present a comparative evaluation of select plasmid-based genetic code expansion systems and a detailed analysis of suppression efficiency with different UAAs and in different cell lines.

Abstract
Lysine acylations, a family of diverse protein modifications varying in acyl-group length, charge, and saturation, are linked to many important physiological processes. Only a small set of substrate-promiscuous lysine acetyltransferases and deacetylases (KDACs) install and remove this vast variety of modifications. Engineered KDACs that remove only one type of acylation would help to dissect the different contributions of distinct acylations. We developed a bacterial selection system for the directed evolution of KDACs and identified variants up to 400 times more selective for butyryl-lysine compared to crotonyl-lysine. Structural analyses revealed that the enzyme adopts different conformational states depending on the type of acylation of the bound peptide. We used the butyryl-selective KDAC variant to shift the cellular acylation spectrum towards increased lysine crotonylation. These new enzymes will help in dissecting the roles of different lysine acylations in cell physiology.

Abstract
Although noncanonical amino acids (ncAAs) were first incorporated into phage libraries through amber suppression nearly two decades ago, their application for use in drug discovery has been limited due to inherent library bias towards sense-containing phages. Here, we report a technique based on superinfection immunity of phages to enrich amber-containing clones, thus avoiding the observed bias that has hindered incorporation of ncAAs into phage libraries. We then take advantage of this technique for development of active site-directed ligand evolution of peptides, where the ncAA serves as an anchor to direct the binding of its peptides to the target’s active site. To demonstrate this, phage-displayed peptide libraries are developed that contain a genetically encoded butyryl lysine and are subsequently used to select for ligands that bind SIRT2. These ligands are then modified to develop low nanomolar inhibitors of SIRT2. Most epigenetic regulator inhibitors target tunnels of active sites, rather than the peptide binding groove, leading to concerns with low selectivity. Here the authors use an amber obligate phage library to rapidly identify isoform-selective inhibitors of SIRT2.

Abstract
Site-specific introduction of bioorthogonal handles into biomolecules provides powerful tools for studying and manipulating the structures and functions of proteins. Recent advances in bioorthogonal chemistry demonstrate that tetrazine-based bioorthogonal cycloaddition is a particularly useful methodology due to its high reactivity, biological selectivity, and turn-on property for fluorescence imaging. Despite its broad applications in protein labeling and imaging, utilization of tetrazine-based bioorthogonal cycloaddition has been limited to date by the requirement of a hydrophobic strained alkene reactive moiety. Circumventing this structural requirement, we report the site-specific incorporation of noncanonical amino acids (ncAAs) with a small isocyanide (or isonitrile) group into proteins in both bacterial and mammalian cells. We showed that under physiological conditions and in the absence of a catalyst these isocyanide-containing ncAAs could react selectively with tetrazine molecules via [4 + 1]-cycloaddition, thus providing a versatile bioorthogonal handle for site-specific protein labeling and protein decaging. Significantly, these bioorthogonal reactions between isocyanides and tetrazines also provide a unique mechanism for the activation of tetrazine-quenched fluorophores. The addition of these isocyanide-containing ncAAs to the list of 20 commonly used, naturally occurring amino acids expands our repertoire of reagents for bioorthogonal chemistry, therefore enabling new biological applications ranging from protein labeling and imaging studies to the chemical activation of proteins.

Abstract
Genetic code expansion allows unnatural (non-canonical) amino acid incorporation into proteins of interest by repurposing the cellular translation machinery. The development of this technique has enabled site-specific incorporation of many structurally and chemically diverse amino acids, facilitating a plethora of applications, including protein imaging, engineering, mechanistic and structural investigations, and functional regulation. Particularly, genetic code expansion provides great tools to study mammalian proteins, of which dysregulations often have important implications in health. In recent years, a series of methods has been developed to modulate protein function through genetically incorporated unnatural amino acids. In this review, we will first discuss the basic concept of genetic code expansion and give an up-to-date list of amino acids that can be incorporated into proteins in mammalian cells. We then focus on the use of unnatural amino acids to activate, inhibit, or reversibly modulate protein function by translational, optical or chemical control. The features of each approach will also be highlighted.

Abstract
A foundation of genetic code expansion is the evolution of orthogonal aminoacyl-tRNA synthetase to recognize a non-canonical amino acid, which typically involves read-through of amber stop codon in the genes used in selection. The process is time-consuming, labor-intensive, and susceptible to certain bias. As a complementation, herein, we rationally designed a function-based method to directed evolution of aminoacyl-tRNA synthetase for acylated lysine derivatives.

Abstract
Post-translational modifications on histone proteins play critical roles in the regulation of chromatin structure and all DNA-templated processes. Accumulating evidence suggests that these covalent modifications can directly alter chromatin structure, or they can modulate activities of chromatin-modifying and -remodeling factors. Studying these modifications in the context of the nucleosome, the basic subunit of chromatin, is thus of great interest; however, the generation of specifically modified nucleosomes remains challenging. This is especially problematic for most structural biology approaches in which a large amount of material is often needed. Here we discuss the strategies currently available for generation of these substrates. We in particular focus on novel ideas and discuss challenges in the application to structural biology studies.

Abstract
Expanding the genetic code to enable the incorporation of unnatural amino acids into proteins in biological systems provides a powerful tool for studying protein structure and function. While this technology has been mostly developed and applied in bacterial and mammalian cells, it recently expanded into animals, including worms, fruit flies, zebrafish, and mice. In this review, we highlight recent advances toward the methodology development of genetic code expansion in animal model organisms. We further illustrate the applications, including proteomic labeling in fruit flies and mice and optical control of protein function in mice and zebrafish. We summarize the challenges of unnatural amino acid mutagenesis in animals and the promising directions toward broad application of this emerging technology.

Abstract
In nature, a limited, conservative set of amino acids are utilized to synthesize proteins. Genetic code expansion technique reassigns codons and incorporates noncanonical amino acids (ncAAs) through orthogonal aminoacyl-tRNA synthetase (aaRS)/tRNA pairs. The past decade has witnessed the rapid growth in diversity and scope for therapeutic applications of this technology. Here, we provided an update on the recent progress using genetic code expansion in the following areas: antibody-drug conjugates (ADCs), bispecific antibodies (BsAb), immunotherapies, long-lasting protein therapeutics, biosynthesized peptides, engineered viruses and cells, as well as other therapeutic related applications, where the technique was used to elucidate the mechanisms of biotherapeutics and drug targets.

Abstract
In the regulation processes of gene expression, genomic DNA and nuclear proteins, including histone proteins, cooperate with each other, leading to the distinctive functions of eukaryotic cells such as pluripotency and differentiation. Chemical modification of histone proteins and DNA has been revealed as one of the major driving forces in the complicated epigenetic regulation system. However, understanding of the precise molecular mechanisms is still limited. To address this issue, researchers have proposed both biological and chemical strategies for the preparation and detection of modified proteins and nucleic acids. In this review, we focus on chemical methods around the field of epigenetics. Chemical protein synthesis has enabled the preparation of site-specifically modified histones and their successful application to various in vitro assays, which have emphasized the significance of posttranslational modifications of interest. We also review the modification-specific chemical reactions against synthetic and genomic DNA, which enabled discrimination of several modified bases at single-base resolution.

Abstract
Nowadays advanced mass spectrometry techniques make the identification of protein posttranslational modifications (PTMs) much easier than ever before. A series of proteomic studies have demonstrated that large numbers of proteins in cells are modified by phosphorylation, acetylation and many other types of PTMs. However, only limited studies have been performed to validate or characterize those identified modification targets, mostly because PTMs are very dynamic, undergoing large changes in different growth stages or conditions. To overcome this issue, the genetic code expansion strategy has been introduced into PTM studies to genetically incorporate modified amino acids directly into desired positions of target proteins. Without using modifying enzymes, the genetic code expansion strategy could generate homogeneously modified proteins, thus providing powerful tools for PTM studies. In this review, we summarized recent development of genetic code expansion in PTM studies for research groups in this field.

Abstract
Reversible post-translational modification (PTM) is a powerful and ubiquitous mechanism to regulate protein function. The mechanistic basis of the associated functional regulation by PTMs often involves the recruitment of interaction partners that selectively bind the modified protein. Identifying such functionally important protein-protein interactions that are uniquely triggered by PTMs remains difficult due to several technical challenges. To address this, here we develop technology to site-specifically incorporate two distinct noncanonical amino acids into recombinant proteins: one modeling a PTM of interest and the second harboring a photoaffinity probe. Using lysine-23 acetylation of histone 3 as a model system, we show that such dual-labeled "protein probes" can covalently capture its "reader" protein.

Abstract
Our understanding of the complex molecular processes of living organisms at the molecular level is growing exponentially. This knowledge, together with a powerful arsenal of tools for manipulating the structures of macromolecules, is allowing chemists to to harness and reprogram the cellular machinery in ways previously unimaged. Here we review one example in which the genetic code itself has been expanded with new building blocks that allow us to probe and manipulate the structures and functions of proteins with unprecedented precision.

Abstract
Exciting new technological developments have pushed the boundaries of structural biology, and have enabled studies of biological macromolecules and assemblies that would have been unthinkable not long ago. Yet, the enhanced capabilities of structural biologists to pry into the complex molecular world have also placed new demands on the abilities of protein engineers to reproduce this complexity into the test tube. With this challenge in mind, we review the contents of the modern molecular engineering toolbox that allow the manipulation of proteins in a site-specific and chemically well-defined fashion. Thus, we cover concepts related to the modification of cysteines and other natural amino acids, native chemical ligation, intein and sortase-based approaches, amber suppression, as well as chemical and enzymatic bio-conjugation strategies. We also describe how these tools can be used to aid methodology development in X-ray crystallography, nuclear magnetic resonance, cryo-electron microscopy and in the studies of dynamic interactions. It is our hope that this monograph will inspire structural biologists and protein engineers alike to apply these tools to novel systems, and to enhance and broaden their scope to meet the outstanding challenges in understanding the molecular basis of cellular processes and disease.
