Reaction
2 S-adenosyl-L-methionine + a [histone H3]-L-lysine9 = 2 S-adenosyl-L-homocysteine + a [histone H3]-N6,N6-dimethyl-L-lysine9 (overall reaction)
(1a) S-adenosyl-L-methionine + a [histone H3]-L-lysine9 = S-adenosyl-L-homocysteine + a [histone H3]-N6-methyl-L-lysine9
(1b) S-adenosyl-L-methionine + a [histone H3]-N6-methyl-L-lysine9 = S-adenosyl-L-homocysteine + a [histone H3]-N6,N6-dimethyl-L-lysine9
Systematic Name
S-adenosyl-L-methionine:[histone H3]-L-lysine9 N6-dimethyltransferase
Function
This entry describes several enzymes, characterized from plants, that successively methylate the L-lysine-9 residue of histone H3 (H3K9) twice, ultimately generating a dimethylated form. These modifications influence the binding of chromatin-associated proteins. In general, the methylation of H3K9 leads to transcriptional repression of the affected target genes. cf. EC 2.1.1.367, [histone H3]-lysine9 N-methyltransferase, EC 2.1.1.366, [histone H3]-N6,N6-dimethyl-lysine9 N-methyltransferase, and EC 2.1.1.355, [histone H3]-lysine9 N-trimethyltransferase.
