Abstract
The chemical synthesis of homogeneously ubiquitylated histones is a powerful approach to decipher histone ubiquitylation-dependent epigenetic regulation. Among the various methods, α-halogen ketone-mediated conjugation chemistry has recently been an attractive strategy to generate single-monoubiquitylated histones for biochemical and structural studies. Herein, we report the use of this strategy to prepare not only dual- and even triple-monoubiquitylated histones but also diubiquitin-modified histones. We were surprised to find that the synthetic efficiencies of multi-monoubiquitylated histones were comparable to those of single-monoubiquitylated ones, suggesting that this strategy is highly tolerant to the number of ubiquitin monomers installed onto histones. The facile generation of a series of single-, dual-, and triple-monoubiquitylated H3 proteins enabled us to evaluate the influence of ubiquitylation patterns on the binding of DNA methyltransferase 1 (DNMT1) to nucleosomes. Our study highlights the potential of site-specific conjugation chemistry to generate chemically defined histones for epigenetic studies.

Abstract
Ubiquitination plays a crucial role in controlling various biological processes such as translation, DNA repair and immune response. Protein degradation for example, is one of the main processes which is controlled by the ubiquitin system and has significant implications on human health. In order to investigate these processes and the roles played by different ubiquitination patterns on biological systems, homogeneously ubiquitinated proteins are needed. Notably, these conjugates that are made enzymatically in cells cannot be easily obtained in large amounts and high homogeneity by employing such strategies. Therefore, chemical and semisynthetic approaches have emerged to prepare different ubiquitinated proteins. In this review, we will present the key synthetic strategies and their applications for the preparation of various ubiquitinated proteins. Furthermore, the use of these precious conjugates in different biochemical and functional studies will be highlighted.

Abstract
Posttranslational modifications (PTMs) dramatically expand the functional diversity of the proteome. The precise addition and removal of PTMs appears to modulate protein structure and function and control key regulatory processes in living systems. Deciphering how particular PTMs affect protein activity is a current frontier in biology and medicine. The large number of PTMs which can appear in several distinct positions, states, and combinations makes preparing such complex analogs using conventional biological and chemical tools challenging. Strategies to access homogeneous and precisely modified proteins with desired PTMs at selected sites and in feasible quantities are critical to interpreting their molecular code. Here, we summarize recent advances in posttranslational chemical mutagenesis and late-stage functionalization chemistry to transfer novel PTM mimicry into recombinant proteins with emphasis on novel transformations.

Abstract
Posttranslational modifications, typically small chemical tags attached on amino acids following protein biosynthesis, have a profound effect on protein structure and function. Numerous chemically and structurally diverse posttranslational modifications, including methylation, acetylation, hydroxylation, and ubiquitination, have been identified and characterised on lysine residues in proteins. In this feature article, we focus on chemical tools that rely on the site-specific incorporation of unnatural amino acids into peptides and proteins to probe posttranslational modifications of lysine. We highlight that simple amino acid mimics enable detailed mechanistic and functional assignment of enzymes that install and remove such modifications, and proteins that specifically recognise lysine posttranslational modifications.

Abstract
The reversible and dynamic post-translational modifications (PTMs) of histones in eukaryotic chromatin are intimately connected to cell development and gene function, and abnormal regulation of PTMs can result in cancer and neurodegenerative diseases. Specific combinations of these modifications are mediated by a series of chromatin proteins that write, erase, and read the "histone codes," but mechanistic studies of the precise biochemical and structural relationships between different sets of modifications and their effects on chromatin function constitute a unique challenge to canonical biochemical approaches. In the past decade, the development and application of chemical methods for investigating histone PTM crosstalks has received considerable attention in the field of chemical biology. In this review, taking the functional crosstalk between H2B ubiquitylation at Lys120 (H2BK120ub) and H3 methylation at Lys79 (H3K79me) as a typical example, we survey recent developments of different chemical methods, in particular, protein synthetic chemistry and protein-based chemical probes, for studying the mechanism of the functional crosstalks of histone PTMs.

Abstract
Coupling reagents play crucial roles in the iterative construction of amide bonds for the synthesis of peptides and peptide-based derivatives. The novel DIC/Oxyma condensation system featured with the low risk of explosion displayed remarkable abilities to inhibit racemization, along with efficient coupling efficiency in both manual and automated syntheses. Nevertheless, an ideal reaction molar ratio in DIC/Oxyma condensation system and the moderate reaction temperature by manual synthesis remain to be further investigated. Herein, the synthetic efficiencies of different reaction ratios between DIC and Oxyma under moderate reaction temperature were systematically evaluated. The robustness and efficiency of DIC/Oxyma condensation system are validated by the rapid synthesis of linear centipede toxin RhTx. Different folding strategies were applied for the construction of disulfide bridges in RhTx, which was further confirmed in assays of circular dichroism and patch-clamp electrophysiology evaluation. This work establishes the DIC/Oxyma-based accelerated synthesis of peptides under moderate condensation conditions, which is especially useful for the manual synthesis of peptides. Besides, the strategy presented here provides robust technical supports for the large-scale synthesis and oxidative folding of RhTx.

Abstract
Ubiquitination is an important posttranslation modification (PTM) that regulates a variety of cellular processes, including protein degradation, DNA repair, and viral infections. In this process, the C-terminal carboxyl group of ubiquitin (Ub) or poly-Ub is attached to the ε-amine of lysine (Lys) side chain of an acceptor protein through an isopeptide bond. Studying a molecular mechanism of ubiquitination and deubiquitination is fundamental for unraveling its precise role in health and disease and hence crucial for drug development. Enzymatic approaches for protein ubiquitination possess limited ability to selectivity install Ub or Ub chain on the desired position of an acceptor protein and often lead to heterogeneous mixtures. In the past decades, chemical protein (semi)synthesis has been proved to be an efficient tool to facilitate site-specific protein ubiquitination, which significantly contributes to decode the Ub signal at molecular and structural levels. In this review, we summarize the synthetic strategies developed for protein ubiquitination, and the achievements to generate monoubiquitinated, di-ubiquitinated, and tetraubiquitinated proteins with native isopeptide and ester bonds.

Abstract
Mono-ubiquitination on H2B (H2Bub1) is an evolutionarily conserved histone post-translational modification implicated in various important physiological processes including DNA replication, transcription activation, and DNA damage repair. The Bre1/Rad6 ubiquitination machinery is currently considered to be the sole writer of H2Bub1, but the mechanistic basis by which it operates is unclear. Recently, the RING-type E3 ligase Bre1 was proposed to associate with the E2 enzyme Rad6 through a novel interaction between Bre1 RBD (Rad6 binding domain) and Rad6; and the RING domain of Bre1 that is responsible for the nucleosomal acidic patch binding also interacts with Rad6 to stimulate its catalytic activity. Recent discoveries have yielded evidence for the phenomenon of liquid-liquid phase separation in the context of H2Bub1, and its regulation by other histone post-translational modifications. This review summarizes current knowledge about Bre1/Rad6-mediated H2B ubiquitination, including the physiological functions and the molecular basis for writing and regulation of this central histone ubiquitin mark. Possible models for the Bre1/Rad6 machinery bound to nucleosomes bearing different modifications in the writing step are also disclosed.

Abstract
We report an Fmoc-compatible and external-thiol-free method of peptide C-terminus thioesterification with cysteinylprolyl imide. The newly synthesized structure, i.e., cysteinylprolyl-thiazolidinone, provided high conversion and sequence-independent fast kinetics (90 min) in the diketopiperazine thioester formation under relatively mild conditions: pH 6.0, 37 °C. Employing this thioesterification method, we synthesized histone H3.2 bearing K56 acetylation.

Abstract
Histone ubiquitylation and deubiquitylation processes and the mechanisms of their regulation are closely relevant to the field of epigenetics. Recently, the deubiquitylating enzyme USP51 was reported to selectively cleave ubiquitylation on histone H2A at K13 or K15 (i.e., H2AK13Ub and H2AK15Ub), but not at K119 (i.e., H2AK119Ub), in nucleosomes in vivo. To elucidate the mechanism for the selectivity of USP51, we constructed structurally well-defined in vitro protein systems with a ubiquitin modification at precise sites. A total chemical protein synthesis procedure was developed, wherein hydrazide-based native chemical ligation was used to efficiently generate five ubiquitylated histones (H2AK13Ub, H2AK15Ub, H2AK119Ub, H2BK34Ub, and H2BK120Ub). These synthetic ubiquitylated histones were assembled into nucleosomes and subjected to in vitro USP51 deubiquitylation assays. Surprisingly, USP51 did not show preference between H2AK13/15Ub and H2AK119Ub, in contrast to previous in vivo observations. Accordingly, an understanding of the selectivity of USP51 may require consideration of other factors, such as alternative pre-existing histone modifications, competitive reader proteins, or different nucleosome quality among the in vivo extraction nucleosome and the in vitro reconstitution one. Further experiments established that USP51 in vitro could deubiquitylate a nucleosome carrying H2BK120Ub, but not H2BK34Ub. Molecular dynamics simulations suggested that USP51-catalyzed hydrolysis of ubiquitylated nucleosomes was affected by steric hindrance of the isopeptide bond.

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
Histone modifications dynamically regulate chromatin structure and function, thereby mediating many processes that require access to DNA. Chemical protein synthesis has emerged as a powerful approach for generating homogeneously modified histone analogues in workable amounts for subsequent incorporation into nucleosome arrays for biochemical, functional and structural studies. This short review focuses on the strength of total chemical protein synthesis and semisynthetic approaches to generate ubiquitylated histones in their native or non-native forms and the utility of these analogues to decode the role of ubiquitylation in epigenetics.

Abstract
In the post-genome era, epigenetics has received increasing attentions in recent years. The post-translational modifications (PTMs) of four core histones play central roles in epigenetic regulation of eukaryotic genome by either directly altering the biophysical properties of nucleosomes or by recruiting other effector proteins. In order to study the biological functions and structural mechanisms of these histone PTMs, an obligatory step is to prepare a sufficient amount of homogeneously modified histones. This task cannot be fully accomplished either by recombinant technology or enzymatic modification. In this context, synthetic chemists have developed novel protein synthetic tools and state-of-the-art chemical ligation strategies for the preparation of homologous modified histones. In this review, we summarize the recent advances in the preparation of modified histones, focusing on the total chemical synthesis strategies. The importance and potential of synthetic chemistry for the study of histone code will be also discussed.
