EC 2.1.1.367

Accepted name: [histone H3]-lysine9 N-methyltransferase

Reaction: S-adenosyl-L-methionine + a [histone H3]-L-lysine9 = S-adenosyl-L-homocysteine + a [histone H3]-N6-methyl-L-lysine9

Other name(s): PRDM3 (gene name); PRDM16 (gene name)

Systematic name: S-adenosyl-L-methionine:[histone H3]-L-lysine9 N6-methyltransferase

Comments: This entry describes several enzymes that methylate the L-lysine-9 residue of histone H3 (H3K9) only once, generating a monomethylated form. These modifications influence the binding of chromatin-associated proteins. cf. EC 2.1.1.368, [histone H3]-lysine9 N-dimethyltransferase, EC 2.1.1.355, [histone H3]-lysine9 N-trimethyltransferase, and EC 2.1.1.366, [histone H3]-N6,N6-dimethyl-lysine9 N-methyltransferase.
