Abstract
An electrophilic 5-methylene-2-pyrrolone modification (KMP ) is produced at lysine residues of histone proteins in nucleosome core particles upon reaction with a commonly formed DNA lesion (C4-AP). The nonenzymatic KMP modification is also generated in the histones of HeLa cells treated with the antitumor agent, bleomycin that oxidizes DNA and forms C4-AP. This nonenzymatic covalent histone modification has the same charge as the N-acetyllysine (KAc ) modification but is more electrophilic. In this study we show that KMP -containing histone peptides are recognized by, and covalently modify bromodomain proteins that are KAc readers. Distinct selectivity preferences for covalent bromodomain modification are observed following incubation with KMP -containing peptides of different sequence. MS/MS analysis of 3 covalently modified bromodomain proteins confirmed that Cys adduction was selective. The modified Cys was not always proximal to the KAc binding site, indicating that KMP -containing peptide interaction with bromodomain protein is distinct from the former. Analysis of protein adduction yields as a function of bromodomain pH at which the protein charge is zero (pI) or cysteine solvent accessible surface area are also consistent with non-promiscuous interaction between the proteins and electrophilic peptides. These data suggest that intracellular formation of KMP could affect cellular function and viability by modifying proteins that regulate genetic expression.

Abstract
Evaluating the significance of various forms of DNA damage is complicated by discoveries that some lesions inactivate repair enzymes or produce more deleterious forms of damage. Histone lysines within nucleosomes react with the commonly produced C4'-oxidized abasic site (C4-AP) to concomitantly yield an electrophilic modification (KMP) on lysine and DNA strand scission. We developed a chemoproteomic approach to identify KMP in HeLa cells. More than 60 000 KMP-modified histones are produced per cell. Using LC-MS/MS, we detected KMP at 17 of the 57 lysine residues distributed throughout the four core histone proteins. Therefore, KMP constitutes a DNA damage-induced, nonenzymatic histone post-translational modification. KMP formation suggests that downstream processes resulting from DNA damage could have ramifications on cells.

Abstract
Hairpin pyrrole-imidazole polyamides (hPIPs) and their chlorambucil (Chb) conjugates (hPIP-Chbs) can alkylate DNA in a sequence-specific manner, and have been studied as anticancer drugs. Here, we conjugated Chb to a cyclic PIP (cPIP), which is known to have a higher binding affinity than the corresponding hPIP, and investigated the DNA alkylation properties of the resulting cPIP-Chb using the optimized capillary electrophoresis method and conventional HPLC product analysis. cPIP-Chb conjugate 3 showed higher alkylation activity at its binding sites than did hPIP-Chb conjugates 1 and 2. Subsequent HPLC analysis revealed that the alkylation site of conjugate 3, which was identified by capillary electrophoresis, was reliable and that conjugate 3 alkylates the N3 position of adenine as do hPIP-Chbs. Moreover, conjugate 3 showed higher cytotoxicity against LNCaP prostate cancer cells than did conjugate 1 and cytotoxicity comparable to that of conjugate 2. These results suggest that cPIP-Chbs could be novel DNA alkylating anticancer drugs.

Abstract
Nucleosomes, which are the fundamental building blocks of chromatin, are highly dynamic, they play vital roles in the formation of higher-order chromatin structures and orchestrate gene regulation. Nucleosome structures, histone modifications, nucleosome-binding proteins, and their functions are being gradually unravelled with the development of epigenetics. With the continuous development of research approaches such as cryo-EM, FRET and next-generation sequencing for genome-wide analysis of nucleosomes, the understanding of nucleosomes is getting wider and deeper. Herein, we review recent progress in research on nucleosomes and epigenetics, from nucleosome structure to chromatin formation, with a focus on chemical aspects. Basic knowledge of the nucleosome (nucleosome structure, nucleosome position sequence, nucleosome assembly and remodeling), epigenetic modifications, chromatin structure, chemical biology methods and nucleosome, observation nucleosome by AFM, phase separation and nucleosomes are described in this review.

Abstract
N7-Methyl-2'-deoxyguanosine (MdG) is the major damage product in DNA produced by methylating agents, but it often thought to be nontoxic and nonmutagenic. MdG is chemically unstable. An abasic site (AP) is the major product produced from MdG under physiologically relevant conditions. AP formation is frequently considered to be responsible for the cytotoxic effects of MdG, but the reaction is suppressed in nucleosome core particles (NCPs). Recently, it was discovered that histone proteins form reversible DNA-protein cross-links (DPCs) with MdG in reconstituted NCPs, as well as in methylmethanesulfonate (MMS) treated cells. In this study, the formation and reactivity of MdG in MMS treated NCPs was examined at single nucleotide resolution. Sequences consisting of three or more consecutive dGs are more reactive with MMS. The efficiency and selectivity of MdG formation by MMS is largely unaffected within a NCP, although reactivity at several dGs is ∼1.5-2.5-fold higher in NCPs. DPC formation from MdG (DPCMdG) predominates over AP at all positions within the NCP. With few exceptions, DPCMdG yield is strongly dependent upon the accessibility of the major groove containing MdG to lysine-rich histone N-terminal tails. These data indicate that histone-MdG DPC formation will depend upon DNA sequence and translational position within an NCP.

Abstract
Ribonucleotides can be incorporated into DNA through many different cellular processes, and abundant amounts of ribonucleotides are detected in genomic DNA. Embedded ribonucleotides lead to genomic instability through either spontaneous ribonucleotide cleavage via internal transesterification or by inducing mutagenesis, recombination, and chromosome rearrangements. Ribonucleotides misincorporated in genomic DNA can be removed by the ribonucleotide excision repair (RER) pathway in which RNase HII initiates the repair by cleaving the 5'-phosphate of the ribonucleotide. Herein, based on in vitro reconstituted nucleosome core particles (NCPs) containing a single ribonucleotide at different positions, we studied the kinetics of ribonucleotide cleavage via the internal transesterification reaction and repair of the ribonucleotides by RNase HII in NCPs. Our results show that ribonucleotide cleavage via the internal transesterification in NCPs is suppressed compared to that in free DNA. DNA bending and structural rigidity account for the suppressed ribonucleotide cleavage in NCPs. Ribonucleotide repair by RNase HII in NCPs exhibits a strong correlation between the translational and rotational positions of the ribonucleotides. An embedded ribonucleotide located at the entry site while facing outward in NCP is repaired as efficiently as that in free DNA. However, the repair of those located in the central part of NCPs and facing inward are inhibited by up to 273-fold relative to those in free dsDNA. The difference in repair efficiency appears to arise from their different accessibility to repair enzymes in NCPs. This study reveals that a ribonucleotide misincorporated in DNA assembled into NCPs is protected against cleavage. Hence, the spontaneous cleavage of the misincorporated ribonucleotides under physiological conditions is not an essential threat to the stability of chromatin DNA. Instead, their decreased repair efficiency in NCPs may result in numerous and persistent ribonucleotides in genomic DNA, which could exert other deleterious effects on DNA such as mutagenesis and recombination.
