Web10 dec. 2024 · In eukaryotes, histone acetylation catalyzed by histone acetyltransferase (HAT) has been demonstrated to be critical for various physiological processes. However, the biological functions of HAT and the underlying mechanism by which HAT-regulated processes are involved in fungal development and virulence in the human opportunistic … WebHistones are acetylated by acetyltransferases, which transfer acetyl groups from acetyl-CoA to histone lysine residues. Acetyl-CoA is a central metabolite that can be produced via several metabolic pathways involved in pyruvate, citrate, acetate, and fatty acid β-oxidation metabolism ( 5 ).
