Abstract
Ubiquitination is a key post-translational modification on protein lysine sidechains known to impact protein stability, signal transduction cascades, protein-protein interactions, and beyond. Great strides have been made towards developing new methods to generate discrete chains of polyubiquitin and conjugate them onto proteins site-specifically, with methods ranging from chemical synthetic approaches, to enzymatic approaches and many in between. Previous work has demonstrated the utility of engineered variants of the bacterial transpeptidase enzyme sortase (SrtA) for conjugation of ubiquitin site-specifically onto target proteins. In this manuscript, we've combined the classical E1/E2-mediated polyubiquitin chain extension approach with sortase-mediated ligation and click chemistry to enable the generation of mono, di, and triubiquitinated proteins sfGFP and PCNA. We demonstrate the utility of this strategy to generate both K48-linked and K63-linked polyubiquitins and attach them both N-terminally and site-specifically to the proteins of interest. Further, we highlight differential activity between two commonly employed sortase variants, SrtA 5M and 7M, and demonstrate that while SrtA 7M can be used to conjugate these ubiquitins to substrates, SrtA 5M can be employed to release the ubiquitin from the substrates as well as to cleave C-terminal tags from the ubiquitin variants used. Overall, we envision that this approach is broadly applicable to readily generate discrete polyubiquitin chains of any linkage type that is accessible via E1/E2 systems and conjugate site-specifically onto proteins of interest, thus granting access to bespoke ubiquitinated proteins that are not currently possible.

Abstract
Topological transformations and permutations of proteins have attracted significant interest as strategies to generate new protein functionalities or stability. These efforts have mainly been inspired by naturally occurring post-translational modifications, such as head-to-tail cyclization, circular permutation, or lasso-like entanglement. Such approaches can be realized experimentally via genetic encoding, in the case of circular permutation, or via enzymatic processing, in the case of cyclization. Notably, these previously described strategies leave the polypeptide backbone orientation unaltered. Here we describe an unnatural protein permutation, the protein domain inversion, whereby a C-terminal portion of a protein is enzymatically inverted from the canonical N-to-C to a C-to-C configuration with respect to the N-terminal part of the protein. The closest conceptually analogous biological process is perhaps the inversion of DNA segments as catalyzed by recombinases. We achieve these inversions using an engineered sortase A, a widely used transpeptidase. Our reactions proceed efficiently under mild conditions at 4-25 °C and are compatible with entirely heterologously-produced protein substrates.

Abstract
The reversible acetylation of specific Lysine residues of histones plays crucial role in the epigenetic regulation of chromatin activity. Importantly, perturbations of acetylation-deacetylation dynamics have important implications for cancer and neurological disorders. There are 18 human HDACs including sirtuins. The site-selective acetyl eraser specificity of HDACs is poorly defined. Deciphering the site specificity preference of HDACs from a gamut of lysine in histones may be critical for targeted inhibitor development and delineation of regulatory mechanisms associated with chromatin. Here, we have interrogated the propensity of HDACs to erase acetyl mark at Lys-5 of H2B namely, H2BK5Ac engineered by a peptide ligation reaction catalyzed by transpeptidase sortase. HDACs and Sirtuins were individually over-expressed in HEK293 cells and the deacetylation propensity of respective cell lysates was evaluated against H2BK5Ac for initial screening of potential acetyl erasers. This screen indicated HDAC1 as the prime eraser of acetyl mark in H2BK5Ac. The propensity of HDAC1 to erase acetyl mark of H2BK5Ac was further probed using semisynthetic designer nucleosomes with whole cell lysates, recombinant enzyme, and specific inhibitors. Consistent with the above data, siRNA knockdown of HDAC1 and closely related HDAC3 in HEK293 cells prevented the loss of H2BK5 acetylation.

Abstract
Histone deacylases are erasers of Nε-acyl-lysine post-translational modifications and have been targeted for decades for the treatment of cancer, neurodegeneration and other disorders. Due to their relatively promiscuous activity on peptide substrates in vitro, it has been challenging to determine the individual targets and substrate identification mechanisms of each isozyme, and they have been considered redundant regulators. In recent years, biochemical and biophysical studies have incorporated the use of reconstituted nucleosomes, which has revealed a diverse and complex arsenal of recognition mechanisms by which histone deacylases may differentiate themselves in vivo. In this review, we first present the peptide-based tools that have helped characterize histone deacylases in vitro to date, and we discuss the new insights that nucleosome tools are providing into their recognition of histone substrates within chromatin. Then, we summarize the powerful semi-synthetic approaches that are moving forward the study of chromatin-associated factors, both in vitro by detailed single-molecule mechanistic studies, and in cells by live chromatin modification. We finally offer our perspective on how these new techniques would advance the study of histone deacylases. We envision that such studies will help elucidate the role of individual isozymes in disease and provide a platform for the development of the next generation of therapeutics.

Bacteria have evolved a diverse set of enzymes that enable them to subvert host defense mechanisms as well as to form part of the prokaryotic immune system. Due to their unique and varied biochemical activities, these bacterial enzymes have emerged as key tools for understanding and investigating biological systems. In this review, we summarize and discuss some of the most prominent bacterial enzymes used for the site-specific modification of proteins, in vivo protein labeling, proximity labeling, interactome mapping, signaling pathway manipulation, and therapeutic discovery. Finally, we provide a perspective on the complementary advantages and limitations of using bacterial enzymes compared with chemical probes for exploring biological systems.

Abstract
Chromatin features are widely used for genome-scale mapping of enhancers. However, discriminating active enhancers from other cis-regulatory elements, predicting enhancer strength and identifying their target genes is challenging. Here we establish histone H2B N-terminus multisite lysine acetylation (H2BNTac) as a signature of active enhancers. H2BNTac prominently marks candidate active enhancers and a subset of promoters and discriminates them from ubiquitously active promoters. Two mechanisms underlie the distinct H2BNTac specificity: (1) unlike H3K27ac, H2BNTac is specifically catalyzed by CBP/p300; (2) H2A-H2B, but not H3-H4, are rapidly exchanged through transcription-induced nucleosome remodeling. H2BNTac-positive candidate enhancers show a high validation rate in orthogonal enhancer activity assays and a vast majority of endogenously active enhancers are marked by H2BNTac and H3K27ac. Notably, H2BNTac intensity predicts enhancer strength and outperforms current state-of-the-art models in predicting CBP/p300 target genes. These findings have broad implications for generating fine-grained enhancer maps and modeling CBP/p300-dependent gene regulation.

Abstract
The reversible acetylation of histone lysine residues is controlled by the action of acetyltransferases and deacetylases (HDACs), which regulate chromatin structure and gene expression. The sirtuins are a family of NAD-dependent HDAC enzymes, and one member, sirtuin 6 (Sirt6), influences DNA repair, transcription, and aging. Here, we demonstrate that Sirt6 is efficient at deacetylating several histone H3 acetylation sites, including its canonical site Lys9, in the context of nucleosomes but not free acetylated histone H3 protein substrates. By installing a chemical warhead at the Lys9 position of histone H3, we trap a catalytically poised Sirt6 in complex with a nucleosome and employ this in cryo-EM structural analysis. The structure of Sirt6 bound to a nucleosome reveals extensive interactions between distinct segments of Sirt6 and the H2A/H2B acidic patch and nucleosomal DNA, which accounts for the rapid deacetylation of nucleosomal H3 sites and the disfavoring of histone H2B acetylation sites. These findings provide a new framework for understanding how HDACs target and regulate chromatin.

Abstract
Lysine acetyltransferase (KAT) enzymes including the p300, MYST, and GCN5 families play major roles in modulating the structure of chromatin and regulating transcription. Because of their dysregulation in various disease states including cancer, efforts to develop inhibitors of KATs have steadily gained momentum. Here we provide an overview of recent progress on the development of high quality chemical probes of the p300 and MYST family of KATs and how they are emerging as useful tools for basic and translational investigation.

Abstract
The post-translational modifications (PTMs) on the tail of histone H3 control chromatin structure and influence epigenetics and gene expression. The current chemical methods including unnatural amino acid incorporation and protein splicing enable preparations of the histone with diverse PTMs in cellular contexts, but they are not applicable to edit native chromatin. The manipulation of histone-modifying enzymes alter the endogenous histone PTMs but the lack of specificity of most histone-modifying enzymes prevents precise control of specific H3 tail PTM patterns. Here we report a new method to edit the N-tail of histone H3 via sortase mediated metathesis (SMM). The sortase can install desired PTM patterns into histone H3 on nucleosomes in vitro and in cellulo. This study expands the application scope of sortase from ligation to metathesis in live cells using cell-penetrating peptides (CPPs). In addition, it offers a strategy to edit PTMs of cellular histone H3 with potential for the development of precise epigenome editing.

Abstract
Classical histone deacetylases (HDACs) are enzymes that can hydrolytically cleave acetyl-Lys in histones and other proteins and serve as established drug targets in some forms of cancer. Class I HDACs 1-3 typically exist in a range of multiprotein complexes inside cells and show distinct biological functions in modulating gene expression. In recent years, it has become possible to purify and analyze the structure and enzymatic properties of several of these HDAC complexes, including CoREST, MiDAC, NuRD, Sin3, SMRT, MIER, and RERE. Here, we summarize what is experimentally established and/or computationally predicted about the structure of these complexes to describe their particular catalytic activities and site-specificities with modified nucleosome substrates.

Abstract
The chemical synthesis of homogeneously modified histones is a powerful approach to quantitatively decipher how post-translational modifications (PTMs) modulate epigenetic events. Herein, we describe the expedient syntheses of a selection of phosphorylated and ubiquitinated H2AX proteins in a strategy integrating expressed protein hydrazinolysis and auxiliary-mediated protein ligation. These modified H2AX proteins were then used to discover that although H2AXS139 phosphorylation can enhance the binding of the DNA damage repair factor 53BP1 to either an unmodified nucleosome or that bearing a single H2AXK15ub or H4K20me2 modification, it augments 53BP1's binding only weakly to nucleosomes bearing both H2AXK15ub and H4K20me2. To better understand why such a trivalent additive effect is lacking, we solved the cryo-EM structure (3.38 Å) of the complex of 53BP1 with the H2AXK15ub/S139ph_H4K20me2 nucleosome, which showed that H2AXS139 phosphorylation distorts the interaction interface between ubiquitin and 53BP1's UDR motif. Our study revealed that there is redundancy in the interplay of multiple histone PTMs, which may be useful for controlling the dynamic distribution of effector proteins onto nucleosomes bearing different histone variants and PTMs in a time-dependent fashion, through specific cellular biochemical events.

[PMID: 35906721 DOI: 10.1002/cbic.202200302] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2022] [Revised: 07/26/2022] [Indexed: 11/08/2022]
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
Sortase A (SrtA)-mediated ligation, a popular method for protein labeling and semi-synthesis, is limited by its reversibility and dependence on the LPxTG motif, where "x" is any amino acid. Here, we report that SrtA can mediate the efficient and irreversible ligation of a protein/peptide containing a C-terminal thioester with another protein/peptide bearing an N-terminal Gly, with broad tolerance for a wide variety of LPxT-derived sequences. This strategy, the thioester-assisted SrtA-mediated ligation, enabled the expedient preparation of proteins bearing various N- or C-terminal labels, including post-translationally modified proteins such as the Ser139-phosphorylated histone H2AX and Lys9-methylated histone H3, with less dependence on the LPxTG motif. Our study validates the chemical modification of substrates as an effective means of augmenting the synthetic capability of existing enzymatic methods.

Abstract
Zinc-dependent histone deacetylases (HDACs) and sirtuins (SIRT) represent two different classes of enzymes which are responsible for deacylation of modified lysine side chains. The repertoire of acyl residues on lysine side chains identified in vivo is rapidly growing, and very recently lysine lactoylation was described to be involved in metabolic reprogramming. Additionally, lysine pyruvoylation represents a marker for aging and liver cirrhosis. Here, we report a systematic analysis of acyl-specificity of human zinc-dependent HDAC and sirtuin isoforms. We identified HDAC3 as a robust delactoylase with several-thousand-fold higher activity as compared to SIRT2, which was claimed to be the major in vivo delactoylase. Additionally, we systematically searched for enzymes, capable of removing pyruvoyl residues from lysine side chains. Using model peptides, we uncovered high depyruvoylase activity for HDAC6 and HDAC8. Interestingly, such substrates have extremely low KM values for both HDAC isoforms, pointing to possible in vivo functions.

Abstract
ConspectusThe sophistication of proteomic analysis has revealed that protein lysine residues are posttranslationally modified by a variety of acyl groups. Protein lysine acetylation regulates metabolism, gene expression, and microtubule formation and has been extensively studied; however, the understanding of the biological significance of other acyl posttranslational modifications (PTMs) is still in its infancy. The acylation of lysine residues is mediated either by acyltransferase "writer" enzymes or by nonenzymatic mechanisms and hydrolase enzymes, termed "erasers", that cleave various acyl PTMs to reverse the modified state. We have studied the human lysine deacylase enzymes, comprising the 11 Zn2+-dependent histone deacetylases (HDACs) and the 7 NAD+-consuming sirtuins (SIRTs), over the past decade. We have thus developed selective inhibitors and molecular probes and have studied the acyl substrate scope of each enzyme using chemically synthesized peptide substrates and photo-cross-linking probes. Recently, we have turned our attention to PTMs containing a stereogenic center, such as ε-N-β-hydroxybutyryllysine (Kbhb) and ε-N-lactyllysine (Kla), that each comprise a pair of mirror image stereoisomers as modifications. Both modifications are found on histones, where they affect gene transcription in response to specific metabolic states, and they are found on cytosolic and mitochondrial enzymes involved in fatty acid oxidation (Kbhb) and glycolysis (Kla), respectively. Thus, chiral modifications to lysine side chains give rise to two distinct diastereomeric products, with separate metabolic origins and potentially different activities exhibited by writer and eraser enzymes. Lysine l-lactylation originates from l-lactate, a major energy carrier produced from pyruvate after glycolysis, and it is highly induced by metabolic states such as the Warburg effect. l-Lactate can possibly be activated by acyl-coenzyme A (CoA) synthetases and transferred to lysine residues by histone acetyltransferases such as p300. d-Lactylation, on the other hand, arises primarily from a nonenzymatic reaction with d-lactylglutathione, an intermediate in the glyoxalase pathway. In addition to their distinct origin, we found that both K(l-la) and K(d-la) modifications are erased by HDACs with different catalytic efficiencies. Also, K(l-bhb) and K(d-bhb) arise from different metabolites but depend on interconnected metabolic pathways, and the two stereoisomers of ε-N-3-hydroxy-3-methylglutaryllysine (Khmg) originate from a single precursor that may then be regulated differently by eraser enzymes. Distinguishing between the individual stereoisomers of PTMs is therefore of crucial importance. In the present Account, we will (1) revisit the long-standing evidence for the distinct production and dynamics of enantiomeric forms of chiral metabolites that serve as ε-N-acyllysine PTMs and (2) highlight the outstanding questions that arise from the recent literature on chiral lysine PTMs resulting from these metabolites.

Abstract
Site-specific protein modification is a widely-used biochemical tool. However, there are many challenges associated with the development of protein modification techniques, in particular, achieving site-specificity, reaction efficiency and versatility. The engineering of peptide ligases and their substrates has been used to address these challenges. This review will focus on sortase, peptidyl asparaginyl ligases (PALs) and variants of subtilisin; detailing how their inherent specificity has been utilised for site-specific protein modification. The review will explore how the engineering of these enzymes and substrates has led to increased reaction efficiency mainly due to enhanced catalytic activity and reduction of reversibility. It will also describe how engineering peptide ligases to broaden their substrate scope is opening up new opportunities to expand the biochemical toolkit, particularly through the development of techniques to conjugate multiple substrates site-specifically onto a protein using orthogonal peptide ligases. We highlight chemical and biochemical strategies taken to optimise peptide and protein modification using peptide ligases.![]()
