Abstract
In classic bioorthogonal labeling experiments, the cell's biosynthetic machinery incorporates bioorthogonal tags, creating tagged biomolecules that are subsequently reacted with a corresponding bioorthogonal partner. This two-step approach labels biomolecules throughout the organism indiscriminate of cell type, which can produce background in applications focused on specific cell populations. In this review, we cover advances in bioorthogonal chemistry that enable targeting of bioorthogonal labeling to a desired cell type. Such cell-selective bioorthogonal labeling is achieved in one of three ways. The first approach restricts labeling to specific cells by cell-selective expression of engineered enzymes that enable the bioorthogonal tag's incorporation. The second approach preferentially localizes the bioorthogonal reagents to the desired cell types to restrict their uptake to the desired cells. Finally, the third approach cages the reactivity of the bioorthogonal reagents, allowing activation of the reaction in specific cells by uncaging the reagents selectively in those cell populations.

Abstract
Protein palmitoylation, with more than 5000 substrates, is the most prevalent form of protein lipidation. Palmitoylated proteins participate in almost all areas of cellular physiology and have been linked to several human diseases. Twenty-three zDHHC enzymes catalyze protein palmitoylation with extensive overlap among the substrates of each zDHHC member. Currently, there is no global strategy to delineate the physiological substrates of individual zDHHC enzymes without perturbing the natural cellular pool. Here, we outline a general approach to accomplish this on the basis of synthetic orthogonal substrates that are only compatible with engineered zDHHC enzymes. We demonstrate the utility of this strategy by validating known substrates and use it to identify novel substrates of two human zDHHC enzymes. Finally, we employ this method to discover and explore conserved palmitoylation in a family of host restriction factors against pathogenic viruses, including SARS-CoV-2.

Abstract
N4-Acetylcytidine (ac4C) has been found to affect a variety of cellular and biological processes. For a mechanistic understanding of the roles of ac4C in biology and disease, we present an antibody-free, fluorine-assisted metabolic sequencing method to detect RNA ac4C, called "FAM-seq". We successfully applied FAM-seq to profile ac4C landscapes in human 293T, HeLa, and MDA cell lines in parallel with the reported acRIP-seq method. By comparison with the classic ac4C antibody sequencing method, we found that FAM-seq is a convenient and reliable method for transcriptome-wide mapping of ac4C. Because this method holds promise for detecting nascent RNA ac4C modifications, we further investigated the role of ac4C in regulating chemotherapy drug resistance in chronic myeloid leukemia. The results indicated that drug development or combination therapy could be enhanced by appreciating the key role of ac4C modification in cancer therapy.

Abstract
The late-stage functionalization of peptides and proteins holds significant promise for drug discovery and facilitates bioorthogonal chemistry. This selective functionalization leads to innovative advances in in vitro and in vivo biological research. However, it is a challenging endeavor to selectively target a certain amino acid or position in the presence of other residues containing reactive groups. Biocatalysis has emerged as a powerful tool for selective, efficient, and economical modifications of molecules. Enzymes that have the ability to modify multiple complex substrates or selectively install nonnative handles have wide applications. Herein, we highlight enzymes with broad substrate tolerance that have been demonstrated to modify a specific amino acid residue in simple or complex peptides and/or proteins at late-stage. The different substrates accepted by these enzymes are mentioned together with the reported downstream bioorthogonal reactions that have benefited from the enzymatic selective modifications.

Abstract
Chemoproteomic profiling is a powerful approach to define the selectivity of small molecules and endogenous metabolites with the human proteome. In addition to mechanistic studies, proteome specificity profiling also has the potential to identify new scaffolds for biomolecular sensing. Here, we report a chemoproteomics-inspired strategy for selective sensing of acetyl-CoA. First, we use chemoproteomic capture experiments to validate the N-terminal acetyltransferase NAA50 as a protein capable of differentiating acetyl-CoA and CoA. A Nanoluc-NAA50 fusion protein retains this specificity and can be used to generate a bioluminescence resonance energy transfer (BRET) signal in the presence of a CoA-linked fluorophore. This enables the development of a ligand displacement assay in which CoA metabolites are detected via their ability to bind the Nanoluc-NAA50 protein "host" and compete binding of the CoA-linked fluorophore "guest". We demonstrate that the specificity of ligand displacement reflects the molecular recognition of the NAA50 host, while the window of dynamic sensing can be controlled by tuning the binding affinity of the CoA-linked fluorophore guest. Finally, we show that the method's specificity for acetyl-CoA can be harnessed for gain-of-signal optical detection of enzyme activity and quantification of acetyl-CoA from cellular samples. Overall, our studies demonstrate the potential of harnessing insights from chemoproteomics for molecular sensing and provide a foundation for future applications in target engagement and selective metabolite detection.

Abstract
Chemicals possessing reactive electrophiles can denature innate proteins leading to undesired toxicity, and the overdose-induced liver injury by drugs containing electrophiles has been one of the major causes of non-approval and withdraw by the US Food and Drug Administration (FDA). Elucidating the associated proteins could guide the future development of therapeutics to circumvent these drugs' toxicities, but was largely limited by the current probing tools due to the steric hindrance of chemical tags including the common "click chemistry" labels. Taking the widely used non-steroidal anti-inflammatory drug acetaminophen (APAP) as an example, we hereby designed and synthesized an APAP analogue using fluorine as a steric-free label. Cell toxicity studies indicated our analogue has similar activity to the parent drug. This analogue was applied to the mouse hepatocellular proteome together with the corresponding desthiobiotin-SH probe for subsequent fluorine-thiol displacement reactions (FTDRs). This set of probes has enabled the labeling and pull-down of hepatocellular target proteins of the APAP metabolite as validated by Western blotting. Our preliminary validation results supported the interaction of APAP with the thioredoxin protein, which is an important redox protein for normal liver function. These results demonstrated that our probes confer minimal steric perturbation and mimic the compounds of interest, allowing for global profiling of interacting proteins. The fluorine-thiol displacement probing system could emerge as a powerful tool to enable the investigation of drug-protein interactions in complex biological environments.

Abstract
The microbiota have emerged as an important factor in host physiology, disease, and response to therapy. These diverse microbes (bacteria, virus, fungi, and protists) encode unique functions and metabolites that regulate intraspecies and interspecies interactions. While the mechanisms of some microbiota species and metabolites have been elucidated, the diversity and abundance of different microbiota species and their associated pathways suggest many more metabolites and mechanisms of action remain to be discovered. In this Perspective, we highlight how the advances in chemical proteomics have provided new opportunities to elucidate the molecular targets of specific microbiota metabolites and reveal new mechanisms of action. The continued development of specific microbiota metabolite reporters and more precise proteomic methods should reveal new microbiota mechanisms of action, therapeutic targets, and biomarkers for a variety of human diseases.

Abstract
Cofactors are required for almost half of all enzyme reactions, but their functions and binding partners are not fully understood even after decades of research. Functionalised cofactor mimics that bind in place of the unmodified cofactor can provide answers, as well as expand the scope of cofactor activity. Through chemical proteomics approaches such as activity-based protein profiling, the interactome and localisation of the native cofactor in its physiological environment can be deciphered and previously uncharacterised proteins annotated. Furthermore, cofactors that supply functional groups to substrate biomolecules can be hijacked by mimics to site-specifically label targets and unravel the complex biology of post-translational protein modification. The diverse activity of cofactors has inspired the design of mimics for use as inhibitors, antibiotic therapeutics, and chemo- and biosensors, and cofactor conjugates have enabled the generation of novel enzymes and artificial DNAzymes.

Abstract
Histone acetyltransferases (HATs, also known as lysine acetyltransferases, KATs) catalyze acetylation of their cognate protein substrates using acetyl-CoA (Ac-CoA) as a cofactor and are involved in various physiological and pathological processes. Advances in mass spectrometry-based proteomics have allowed the discovery of thousands of acetylated proteins and the specific acetylated lysine sites. However, due to the rapid dynamics and functional redundancy of HAT activities, and the limitation of using antibodies to capture acetylated lysines, it is challenging to systematically and precisely define both the substrates and sites directly acetylated by a given HAT. Here, we describe a chemoproteomic approach to identify and profile protein substrates of individual HAT enzymes on the proteomic scale. The approach involves protein engineering to enlarge the Ac-CoA binding pocket of the HAT of interest, such that a mutant form is generated that can use functionalized acyl-CoAs as a cofactor surrogate to bioorthogonally label its protein substrates. The acylated protein substrates can then be chemoselectively conjugated either with a fluorescent probe (for imaging detection) or with a biotin handle (for streptavidin pulldown and chemoproteomic identification). This modular chemical biology approach has been successfully implemented to identify protein substrates of p300, GCN5, and HAT1, and it is expected that this method can be applied to profile and identify the sub-acetylomes of many other HAT enzymes. © 2022 Wiley Periodicals LLC.

Abstract
The family of lysine acetyltransferases (KATs) regulates epigenetics and signaling pathways in eukaryotic cells. So far, knowledge of different KAT members contributing to the cellular acetylome is limited, which limits our understanding of biological functions of KATs in physiology and disease. Here, we found that a clickable acyl-CoA reporter, 3-azidopropanoyl CoA (3AZ-CoA), presented remarkable cell permeability and effectively acylated proteins in cells. We rationally engineered the major KAT member, histone acetyltransferase 1 (HAT1), to generate its mutant forms that displayed excellent bio-orthogonal activity for 3AZ-CoA in substrate labeling. We were able to apply the bio-orthogonal enzyme-cofactor pair combined with SILAC proteomics to achieve HAT1 substrate targeting, enrichment, and proteomic profiling in living cells. A total of 123 protein substrates of HAT1 were disclosed, underlining the multifactorial functions of this important enzyme than hitherto known. This study demonstrates the first example of utilizing bio-orthogonal reporters as a chemoproteomic strategy for substrate mapping of individual KAT isoforms in the native biological contexts.

Abstract
Specific post-translational modification (PTM) states of a protein affect its property and function; understanding their dynamics in cells would provide deep insight into diverse signaling pathways and biological processes. However, it is not trivial to visualize post-translational modifications in a protein- and site-specific manner, especially in a living-cell context. Herein, we review recent advances in the development of molecular imaging tools to detect diverse classes of post-translational proteoforms in individual cells, and their applications in studying precise roles of PTMs in regulating the function of cellular proteins.

Abstract
Lysine acetylation is one of the most basic molecular mechanisms to mediate protein functions in living organisms, and its abnormal regulation has been linked to many diseases. The drug development associated to this process is of great significance but severely hindered by the complex interplay of lysine acetylation and deacetylation in thousands of proteins, and we reasoned that targeting a specific protein acetylation or deacetylation event instead of the related enzymes should be a feasible solution to this issue. Toward this goal, we devised an orthogonal lysine acylation and deacylation (OKAD) system, which potentially could precisely dissect the biological consequence of an individual acetylation or deacetylation event in living cells. The system includes a genetically encoded acylated lysine (PhOAcK) that is not a substrate of endogenous deacetylases, and an evolved sirtuin (CobB2/CobB3) that displays PhOAcK deacylase activities as well as reduced deacetylase activities. We believe the strategy introduced here holds potential for future in-depth biological applications.

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
The field of epigenetics has exploded over the last two decades, revealing an astonishing level of complexity in the way genetic information is stored and accessed in eukaryotes. This expansion of knowledge, which is very much ongoing, has been made possible by the availability of evermore sensitive and precise molecular tools. This review focuses on the increasingly important role that chemistry plays in this burgeoning field. In an effort to make these contributions more accessible to the nonspecialist, we group available chemical approaches into those that allow the covalent structure of the protein and DNA components of chromatin to be manipulated, those that allow the activity of myriad factors that act on chromatin to be controlled, and those that allow the covalent structure and folding of chromatin to be characterized. The application of these tools is illustrated through a series of case studies that highlight how the molecular precision afforded by chemistry is being used to establish causal biochemical relationships at the heart of epigenetic regulation.

Abstract
Supramolecular catalysts emulate the mechanism of enzymes to achieve large rate accelerations and precise selectivity under mild and aqueous conditions. While significant strides have been made in the supramolecular host-promoted synthesis of small molecules, applications of this reactivity to chemoselective and site-selective modification of complex biomolecules remain virtually unexplored. We report here a supramolecular system where coencapsulation of pyridine-borane with a variety of molecules including enones, ketones, aldehydes, oximes, hydrazones, and imines effects efficient reductions under basic aqueous conditions. Upon subjecting unprotected lysine to the host-mediated reductive amination conditions, we observed excellent ε-selectivity, indicating that differential guest binding within the same molecule is possible without sacrificing reactivity. Inspired by the post-translational modification of complex biomolecules by enzymatic systems, we then applied this supramolecular reaction to the site-selective labeling of a single lysine residue in an 11-amino acid peptide chain and human insulin.

Abstract
Protein glycosylation fundamentally impacts biological processes. Nontemplated biosynthesis introduces unparalleled complexity into glycans that needs tools to understand their roles in physiology. The era of quantitative biology is a great opportunity to unravel these roles, especially by mass spectrometry glycoproteomics. However, with high sensitivity come stringent requirements on tool specificity. Bioorthogonal metabolic labeling reagents have been fundamental to studying the cell surface glycoproteome but typically enter a range of different glycans and are thus of limited specificity. Here, we discuss the generation of metabolic 'precision tools' to study particular subtypes of the glycome. A chemical biology tactic termed bump-and-hole engineering generates mutant glycosyltransferases that specifically accommodate bioorthogonal monosaccharides as an enabling technique of glycobiology. We review the groundbreaking discoveries that have led to applying the tactic in the living cell and the implications in the context of current developments in mass spectrometry glycoproteomics.

Abstract
We have developed a novel bioorthogonal reaction that can selectively displace fluorine substitutions alpha to amide bonds. This fluorine-thiol displacement reaction (FTDR) allows for fluorinated cofactors or precursors to be utilized as chemical reporters, hijacking acetyltransferase-mediated acetylation both in vitro and in live cells, which cannot be achieved with azide- or alkyne-based chemical reporters. The fluoroacetamide labels can be further converted to biotin or fluorophore tags using FTDR, enabling the general detection and imaging of acetyl substrates. This strategy may lead to a steric-free labeling platform for substrate proteins, expanding our chemical toolbox for functional annotation of post-translational modifications in a systematic manner.

Abstract
Short-chain acylations of lysine residues in eukaryotic proteins are recognized as essential posttranslational chemical modifications (PTMs) that regulate cellular processes from transcription, cell cycle, metabolism, to signal transduction. Lysine butyrylation was initially discovered as a normal straight chain butyrylation (Knbu). Here we report its structural isomer, branched chain butyrylation, i.e. lysine isobutyrylation (Kibu), existing as a new PTM on nuclear histones. Uniquely, isobutyryl-CoA is derived from valine catabolism and branched chain fatty acid oxidation which is distinct from the metabolism of n-butyryl-CoA. Several histone acetyltransferases were found to possess lysine isobutyryltransferase activity in vitro, especially p300 and HAT1. Transfection and western blot experiments showed that p300 regulated histone isobutyrylation levels in the cell. We resolved the X-ray crystal structures of HAT1 in complex with isobutyryl-CoA that gleaned an atomic level insight into HAT-catalyzed isobutyrylation. RNA-Seq profiling revealed that isobutyrate greatly affected the expression of genes associated with many pivotal biological pathways. Together, our findings identify Kibu as a novel chemical modification mark in histones and suggest its extensive role in regulating epigenetics and cellular physiology.

Abstract
Post-translational modifications, complex formation, subcellular localization, and cell-type-specific expression create functionally distinct protein subpopulations that enable living systems to execute rapid and precise responses to changing conditions. Systems-level analysis of these subproteomes remains challenging, requiring preservation of spatial information or enrichment of species that are transient and present at low abundance. Engineered proteins have emerged as important tools for selective proteomics based on their capacity for highly specific molecular recognition and their genetic targetability. Here, we focus on new developments in protein engineering for selective proteomics of post-translational modifications, protein complexes, subcellular compartments, and cell types. We also address remaining challenges and future opportunities to integrate engineered protein tools across different subproteome scales to map the proteome with unprecedented depth and detail.

Abstract
Histone lysine acetyltransferase (KAT)-catalyzed acetylation of lysine residues in histone tails plays a key role in regulating gene expression in eukaryotes. Here, we examined the role of lysine side chain length in the catalytic activity of human KATs by incorporating shorter and longer lysine analogs into synthetic histone H3 and H4 peptides. The enzymatic activity of MOF, PCAF and GCN5 acetyltransferases towards histone peptides bearing lysine analogs was evaluated using MALDI-TOF MS assays. Our results demonstrate that human KAT enzymes have an ability to catalyze an efficient acetylation of longer lysine analogs, whereas shorter lysine analogs are not substrates for KATs. Kinetics analyses showed that lysine is a superior KAT substrate to its analogs with altered chain length, implying that lysine has an optimal chain length for KAT-catalyzed acetylation reaction.

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
Histone lysine acetyltransferases (KATs) catalyze the transfer of the acetyl group from acetyl Coenzyme A to lysine residues in histones and nonhistone proteins. Here, we report biomolecular studies on epigenetic acetylation and related acylation reactions of lysine and γ-thialysine, a cysteine-derived lysine mimic, which can be site-specifically introduced to histone peptides and histone proteins. Enzyme assays demonstrate that human KATs catalyze an efficient acetylation and propionylation of histone peptides that possess lysine and γ-thialysine. Enzyme kinetics analyses reveal that lysine- and γ-thialysine-containing histone peptides exhibit indistinguishable Km values, whereas small differences in kcat values were observed. This work highlights that γ-thialysine may act as a representative and easily accessible lysine mimic for chemical and biochemical examinations of post-translationally modified histones.

Abstract
Protein acylation, exemplified by lysine acetylation, is a type of indispensable and widespread protein posttranslational modification in eukaryotes. Functional annotation of various lysine acetyltransferases (KATs) is critical to understanding their regulatory roles in abundant biological processes. Traditional radiometric and immunosorbent assays have found broad use in KAT study but have intrinsic limitations. Designing acyl-coenzyme A (CoA) reporter molecules bearing chemoselective chemical warhead groups as surrogates of the native cofactor acetyl-CoA for bioorthogonal labeling of KAT substrates has come into a technical innovation in recent years. This chemical biology platform equips molecular biologists with empowering tools in acyltransferase activity detection and substrate profiling. In the bioorthogonal labeling, protein substrates are first enzymatically modified with a functionalized acyl group. Subsequently, the chemical warhead on the acyl chain conjugates with either an imaging chromophore or an affinity handle or any other appropriate probes through an orthogonal chemical ligation. This bioorganic strategy reformats the chemically inert acetylation and acylation marks into a chemically maneuverable functionality and generates measurable signals without recourse to radioisotopes or antibodies. It offers ample opportunities for facile sensitive detection of KAT activity with temporal and spatial resolutions as well as allows for chemoproteomic profiling of protein acetylation pertaining to specific KATs of interest on the global scale. We reviewed here the past and current advances in bioorthogonal protein acylations and highlighted their wide-spectrum applications. We also discussed the design of other related acyl-CoA and CoA-based chemical probes and their deployment in illuminating protein acetylation and acylation biology.

Abstract
O-Linked α-N-acetylgalactosamine (O-GalNAc) glycans constitute a major part of the human glycome. They are difficult to study because of the complex interplay of 20 distinct glycosyltransferase isoenzymes that initiate this form of glycosylation, the polypeptide N-acetylgalactosaminyltransferases (GalNAc-Ts). Despite proven disease relevance, correlating the activity of individual GalNAc-Ts with biological function remains challenging due to a lack of tools to probe their substrate specificity in a complex biological environment. Here, we develop a "bump-hole" chemical reporter system for studying GalNAc-T activity in vitro. Individual GalNAc-Ts were rationally engineered to contain an enlarged active site (hole) and probed with a newly synthesized collection of 20 (bumped) uridine diphosphate N-acetylgalactosamine (UDP-GalNAc) analogs to identify enzyme-substrate pairs that retain peptide specificities but are otherwise completely orthogonal to native enzyme-substrate pairs. The approach was applicable to multiple GalNAc-T isoenzymes, including GalNAc-T1 and -T2 that prefer nonglycosylated peptide substrates and GalNAcT-10 that prefers a preglycosylated peptide substrate. A detailed investigation of enzyme kinetics and specificities revealed the robustness of the approach to faithfully report on GalNAc-T activity and paves the way for studying substrate specificities in living systems.

Abstract
A continuous flow approach for the synthesis of α-acyloxy ketone derivatives from the corresponding arylglyoxals, isocyanides, and carboxylic acids is described. The target products were obtained in excellent yields in short residence times and with high purities via the first transcription of the microwave-to-flow paradigm to the isocyanide-based Passerini reaction. Furthermore, this methodology allowed a 10-fold scale-up using the same experimental conditions initially established.

Abstract
Lysine acetyltransferases (KATs, also termed histone acetyltransferases, HATs) catalyze the acetylation of substrate lysine residues by employing the cofactor acetyl-coenzyme A (AcCoA), thereby providing a dynamic control mechanism of protein function. Because of their major involvement in cell development and homeostasis, small-molecule modulators of KAT activity are urgently needed to assess their therapeutic potential and for probing their underlying biology. Recent advances in the field suggest that targeting the cofactor binding site represents a promising strategy for identifying potent and selective ligands. Here, we present the synthesis of two functional cofactor-based chemical probes and their usage as mechanistic tools in a broadly applicable assay platform. A fluorescence polarization (FP)-based binding assay was combined with biolayer interferometry competition analysis and a FP competition activity immunoassay to enable easy, reliable, and profound evaluation of ligands that target the KAT cofactor binding site.

Abstract
Histone post-translational modifications are crucial epigenetic mechanisms regulating a variety of biological events. Besides histone lysine acetylation, a repertoire of acylation types have been identified, including formylation, propionylation, butyrylation, crotonylation, 2-hydroxyisobutyrylation, β-hydroxybutyrylation, succinylation, malonylation, glutarylation and benzoylation. From a structural perspective, here we summarize the writers and erasers of histone acylations and explain the molecular basis of these enzymes catalyzing non-acetyl histone acylations with a focus on histone crotonylation and β-hydroxybutyrylation. Histone acylation readout, non-histone acylations and metabolic regulation are also discussed in this review.

Abstract
Successful mapping of the human genome has sparked a widespread interest in deciphering functional information encoded in gene sequences. However, because of the high degree of conservation in sequences along with topological and biochemical similarities among members of a protein superfamily, uncovering physiological role of a particular protein has been a challenging task. Chemical genetic approaches have made significant contributions toward understanding protein function. One such effort, dubbed the bump-and-hole approach, has convincingly demonstrated that engineering at the protein-small molecule interface constitutes a powerful method for elucidating the function of a specific gene product. By manipulating the steric component of protein-ligand interactions in a complementary manner, an orthogonal system is developed to probe a specific enzyme-cofactor pair without interference from related members. This article outlines current efforts to expand the approach for diverse protein classes and their applications. Potential future innovations to address contemporary biological problems are highlighted as well.

Abstract
The side-chain acetylation of lysine residues in histones and non-histone proteins catalyzed by lysine acetyltransferases (KATs) represents a widespread posttranslational modification (PTM) in the eukaryotic cells. Lysine acetylation plays regulatory roles in major cellular pathways inside and outside the nucleus. In particular, KAT-mediated histone acetylation has an effect on all DNA-templated epigenetic processes. Aberrant expression and activation of KATs are commonly observed in human diseases, especially cancer. In recent years, the study of KAT functions in biology and disease has greatly benefited from chemical biology tools and strategies. In this Review, we present the past and current accomplishments in the design of chemical biology approaches for the interrogation of KAT activity and function. These methods and probes are classified according to their mechanisms of action and respective applications, with both strengths and limitations discussed.

Abstract
A systematically designed panel of biorthogonal pro-metabolites was synthesized and evaluated as agents for tracing cellular short chain fatty acylation.
Short chain fatty acids (SCFAs) play a central role in health and disease. One function of these signaling molecules is to serve as precursors for short chain fatty acylation, a class of metabolically-derived posttranslational modifications (PTMs) that are established by lysine acetyltransferases (KATs) and lysine deacetylases (KDACs). Via this mechanism, short chain fatty acylation serves as an integrated reporter of metabolism as well as KAT and KDAC activity, and has the potential to illuminate the role of these processes in disease. However, few methods to study short chain fatty acylation exist. Here we report a bioorthogonal pro-metabolite strategy for profiling short chain fatty acylation in living cells. Inspired by the dietary component tributyrin, we synthesized a panel of ester-caged bioorthogonal short chain fatty acids. Cellular evaluation of these agents led to the discovery of an azido-ester that is metabolized to its cognate acyl-coenzyme A (CoA) and affords robust protein labeling profiles. We comprehensively characterize the metabolic dependence, toxicity, and histone deacetylase (HDAC) inhibitor sensitivity of these bioorthogonal pro-metabolites, and apply an optimized probe to identify novel candidate protein targets of short chain fatty acids in cells. Our studies showcase the utility of bioorthogonal pro-metabolites for unbiased profiling of cellular protein acylation, and suggest new approaches for studying the signaling functions of SCFAs in differentiation and disease.

Abstract
p300 and GCN5 are two representative lysine acetyltransferases (KATs) in mammalian cells. It was recently reported that they possess multiple acyltransferase activities including acetylation, propionylation, and butyrylation of the ε-amino group of lysine residues of histones and non-histone protein substrates. Although thousands of acetylated substrates and acetylation sites have been identified by mass spectrometry-based proteomic screening, our knowledge about the causative connections between individual KAT members and their corresponding sub-acylomes remain very limited. Herein, we applied 3-azidopropionyl CoA (3AZ-CoA) as a bioorthogonal surrogate of acetyl-, propionyl- and butyryl-CoA for KAT substrate identification. We successfully attached the azide as a chemical warhead to cellular substrates of wild-type p300 and engineered GCN5. The substrates were subsequently labeled with biotin tag through the copper-catalyzed azide-alkyne cycloaddition (CuAAC). Following protein enrichment on streptavidin-coated resin, we conducted LC-MS/MS studies from which more than four hundred proteins were identified as GCN5 or p300 substrate candidates. These proteins are either p300- or GCN5-unique or shared by the two KATs and are extensively involved in various biological events including gene expression, cell cycle, and cellular metabolism. We also experimentally validated two novel substrates of GCN5, that is, IQGAP1 and SMC1. These results demonstrate extensive engagement of GCN5 and p300 in cellular pathways and provide new insights into understanding their functions in specific biological processes.

Abstract
Post-translational modifications (PTMs) allot versatility to the biological functions of highly conserved proteins. Recently, modifications to non-histone proteins such as methylation, acetylation, phosphorylation, glycosylation, ubiquitination, and many more have been linked to the regulation of pivotal pathways related to cellular response and stability. Due to the roles these dynamic modifications assume, their dysregulation has been associated with cancer and many other important diseases such as inflammatory disorders and neurodegenerative diseases. For this reason, we present a review and perspective on important post-translational modifications on non-histone proteins, with emphasis on their roles in diseases and small molecule inhibitors developed to target PTM writers. Certain PTMs' contribution to epigenetics has been extensively expounded; yet more efforts will be needed to systematically dissect their roles on non-histone proteins, especially for their relationships with nononcological diseases. Finally, current research approaches for PTM study will be discussed and compared, including limitations and possible improvements.

Abstract
Histone acetylation plays an important role in transcriptional activation. Histones are also modified by chemically diverse acylations that are frequently deposited by p300, a transcriptional coactivator that uses a number of different acyl-CoA cofactors. Here we report that while p300 is a robust acetylase, its activity gets weaker with increasing acyl-CoA chain length. Crystal structures of p300 in complex with propionyl-, crotonyl-, or butyryl-CoA show that the aliphatic portions of these cofactors are bound in the lysine substrate-binding tunnel in a conformation that is incompatible with substrate transfer. Lysine substrate binding is predicted to remodel the acyl-CoA ligands into a conformation compatible with acyl-chain transfer. This remodeling requires that the aliphatic portion of acyl-CoA be accommodated in a hydrophobic pocket in the enzymes active site. The size of the pocket and its aliphatic nature exclude long-chain and charged acyl-CoA variants, presumably explaining the cofactor preference for p300.

Abstract
Chemical genetics offers tools and opportunities to investigate epigenetic processes. Chemical probes targeting epigenetic proteins are increasingly being developed. Epigenetic targets pose distinct challenges to chemical genetics approaches. The ‘bump-and-hole’ approach allows for highly selective single-target inhibition. PROTACS can degrade target proteins to enhance efficacy and selectivity.
Chemical genetics is the use of biologically active small molecules (chemical probes) to investigate the functions of gene products, through the modulation of protein activity. Recent years have seen significant progress in the application of chemical genetics to study epigenetics, following the development of new chemical probes, a growing appreciation of the role of epigenetics in disease and a recognition of the need and utility of high-quality, cell-active chemical probes. In this review, we single out the bromodomain reader domains as a prime example of both the success, and challenges facing chemical genetics. The difficulty in generating single-target selectivity has long been a thorn in the side of chemical genetics, however, recent developments in advanced forms of chemical genetics promise to bypass this, and other, limitations. The ‘bump-and-hole’ approach has now been used to probe — for the first time — the BET bromodomain subfamily with single-target selectivity and may be applicable to other epigenetic domains. Meanwhile, PROTAC compounds have been shown to be significantly more efficacious than standard domain inhibitors, and have the potential to enhance target selectivity.

Abstract
Chromatin is the universal template of genetic information in all eukaryotic organisms. Chemical modifications of the DNA-packaging histone proteins and the DNA bases are crucial signaling events in directing the use and readout of eukaryotic genomes. The enzymes that install and remove these chromatin modifications as well as the proteins that bind these marks govern information that goes beyond the sequence of DNA. Therefore, these so-called epigenetic regulators are intensively studied and represent promising drug targets in modern medicine. We summarize and discuss recent advances in the field of chemical biology that have provided chromatin research with sophisticated tools for investigating the composition, activity, and target sites of chromatin modifying enzymes and reader proteins.

Abstract
Proteins are acylated by a variety of metabolites that regulates many important cellular pathways in all kingdoms of life. Acyl groups in cells can vary in structure from the smallest unit, acetate, to modified long-chain fatty acids, all of which can be activated and covalently attached to diverse amino acid side chains and consequently modulate protein function. For example, acetylation of Lys residues can alter the charge state of proteins and generate new recognition elements for protein-protein interactions. Alternatively, long-chain fatty-acylation targets proteins to membranes and enables spatial control of cell signalling. To facilitate the analysis of protein acylation in biology, acyl analogues bearing alkyne or azide tags have been developed that enable fluorescent imaging and proteomic profiling of modified proteins using bioorthogonal ligation methods. Herein, we summarize the currently available acylation chemical reporters and highlight their utility to discover and quantify the roles of protein acylation in biology.

Abstract
Histone acetyltransferases (HATs) are key players in the epigenetic regulation of gene function. The recent discovery of diverse HAT substrates implies a broad spectrum of cellular functions of HATs. Many pathological processes are also intimately associated with the dysregulation of HAT levels and activities. However, detecting the enzymatic activity of HATs has been challenging, and this has significantly impeded drug discovery. To advance the field, we developed a convenient one-pot, mix-and-read strategy that is capable of directly detecting the acylated histone product through a fluorescent readout. The strategy integrates three technological platforms-bioorthogonal HAT substrate labeling, alkyne-azide click chemistry, and quenching FRET-into one system for effective probing of HAT enzyme activity.

Abstract
Inhibition of the enzymatic activity of histone deacetylase (HDAC) is a promising therapeutic strategy for cancer treatment and several distinct small molecule histone deacetylase inhibitors (HDACi) have been reported. We have previously identified a new class of non-peptide macrocyclic HDACi derived from 14- and 15-membered macrolide skeletons. In these HDACi, the macrocyclic ring is linked to the zinc chelating hydroxamate moiety through a para-substituted aryl-triazole cap group. To further delineate the depth of the SAR of this class of HDACi, we have synthesized series of analogous compounds and investigated the influence of various substitution patterns on their HDAC inhibitory, anti-proliferative and anti-inflammatory activities. We identified compounds 25b and 38f with robust anti-proliferative activities and compound 26f (IC50 47.2 nM) with superior anti-inflammatory (IC50 88 nM) activity relative to SAHA.

Abstract
The finding that chromatin modifications are sensitive to changes in cellular cofactor levels potentially links altered tumor cell metabolism and gene expression. However, the specific enzymes and metabolites that connect these two processes remain obscure. Characterizing these metabolic-epigenetic axes is critical to understanding how metabolism supports signaling in cancer, and developing therapeutic strategies to disrupt this process. Here, we describe a chemical approach to define the metabolic regulation of lysine acetyltransferase (KAT) enzymes. Using a novel chemoproteomic probe, we identify a previously unreported interaction between palmitoyl coenzyme A (palmitoyl-CoA) and KAT enzymes. Further analysis reveals that palmitoyl-CoA is a potent inhibitor of KAT activity and that fatty acyl-CoA precursors reduce cellular histone acetylation levels. These studies implicate fatty acyl-CoAs as endogenous regulators of histone acetylation, and suggest novel strategies for the investigation and metabolic modulation of epigenetic signaling.

Abstract
Poly-ADP-ribose polymerases (PARPs) comprise a family of 17 distinct enzymes that catalyze the transfer of ADP-ribose from nicotinamide adenine dinucleotide (NAD+) to acceptor sites on protein targets. PARPs have been implicated in a number of essential signaling pathways regulating both normal cell function and pathophysiology. To understand the physiological role of each PARP family member in the cell we need to identify the direct targets for each unique PARP in a cellular context. PARP-family member-specific target identification is challenging because of their shared catalytic mechanism and functional redundancy. To address this challenge, we have engineered a PARP variant that efficiently uses an orthogonal NAD+ analog, an analog that endogenous PARPs cannot use, as a substrate for ADP-ribosylation. The protocols in this unit describe a general procedure for using engineered PARP variants-orthogonal NAD+ analog pairs for labeling and identifying the direct targets of the poly-subfamily of PARPs (PARPs 1-3, 5, and 6).
