Background
Histones are subject to a variety of enzyme-catalyzed modifications, including acetylation, methylation, phosphorylation, ubiquitylation, and others. Among these modifications, lysine propionylation (Kpr) has emerged as a newly identified reversible modification that plays a crucial role in controlling protein activity. Structurally similar to lysine acetylation, lysine propionylation is prevalent in both prokaryotes and eukaryotes and has been identified in a wide range of proteins, including histones and non-histone substrates like p53. Recent studies have highlighted the role of histone H3 propionylation at Lys18 in the epigenetic modulation, particularly in chromatin remodeling and transcriptional regulation.
