QM/MM Investigation of Substrate and Product Specificities of Suv4-20h2: How Does This Enzyme Generate Dimethylated H4K20 from Monomethylated Substrate?

Abstract

Protein lysine methyltransferases (PKMTs) catalyze the methylation of lysine residues on histone proteins in the regulation of chromatin structure and gene expression. In contrast to many other PKMTs for which unmodified lysine is the methylation target, the enzymes in the Suv4-20 family are able to generate dimethylated product (H4K20me2) based exclusively… (More)
