| Accepted name: | [histone H3]-lysine4 N-trimethyltransferase | ||||||
| Reaction: | 3 S-adenosyl-L-methionine + a [histone H3]-L-lysine4 = 3 S-adenosyl-L-homocysteine + a [histone H3]-N6,N6,N6-trimethyl-L-lysine4 (overall reaction) (1a) S-adenosyl-L-methionine + a [histone H3]-L-lysine4 = S-adenosyl-L-homocysteine + a [histone H3]-N6-methyl-L-lysine4 (1b) S-adenosyl-L-methionine + a [histone H3]-N6-methyl-L-lysine4 = S-adenosyl-L-homocysteine + a [histone H3]-N6,N6-dimethyl-L-lysine4 (1c) S-adenosyl-L-methionine + a [histone H3]-N6,N6-dimethyl-L-lysine4 = S-adenosyl-L-homocysteine + a [histone H3]-N6,N6,N6-trimethyl-L-lysine4 |

| Systematic name: | S-adenosyl-L-methionine:[histone H3]-L-lysine4 N6-trimethyltransferase | ||||||
| Comments: | This entry describes several enzymes that successively methylate the L-lysine4 residue of histone H3 (H3K4), ultimately generating a trimethylated form. These modifications influence the binding of chromatin-associated proteins. In most cases the trimethylation of this position is associated with gene activation. EC 2.1.1.364, [histone H3]-lysine4 N-methyltransferase, describes enzymes that can catalyse only monomethylation of this substrate (the first sub-reaction of this entry); EC 2.1.1.370, [histone H3]-lysine4 N-dimethyltransferase, describes enzymes that catalyse only dimethylation of this substrate (the first two sub-reactions of this entry) | ||||||
