WebAug 3, 2024 · HISTome2 focuses on the sub-classification of histone proteins as variants and isoforms, post-translational modifications (PTMs) and modifying enzymes for humans ( Homo sapiens ), rat ( Rattus norvegicus) and mouse ( Mus musculus) on one interface for integrative analysis. Additional infrequent histone modifications and their effects are listed in the table below. The presence of O-GlcNAcylation (O-GlcNAc) on serine (S) and threonine (T) histone residues is known to mediate other post-transcriptional histone modifications. The addition and removal of GlcNAc groups are performed by O-…

WebJul 3, 2024 · The coincident emergence of eukaryotes with global oxygenation, which challenged cellular copper utilization, raised the possibility that histones may function in cellular copper homeostasis. We report that the recombinant Xenopus laevis H3-H4 tetramer is an oxidoreductase enzyme that binds Cu 2+ and catalyzes its reduction to Cu 1+ in vitro. WebApr 14, 2024 · A group of researchers, spearheaded by a Penn State team, have captured images of a sirtuin enzyme linked to a nucleosome—a densely packed structure composed of DNA and histone proteins—demonstrating the enzyme’s ability to maneuver the nucleosome assembly and access both DNA and histone proteins, thereby elucidating its …
