Sysname
S-adenosyl-L-methionine:[histone H3]-L-lysine27 N6-dimethyltransferase
Reaction(IUBMB)
2 S-adenosyl-L-methionine + a [histone H3]-L-lysine27 = 2 S-adenosyl-L-homocysteine + a [histone H3]-N6,N6-dimethyl-L-lysine27 (overall reaction);
(1a) S-adenosyl-L-methionine + a [histone H3]-L-lysine27 = S-adenosyl-L-homocysteine + a [histone H3]-N6-methyl-L-lysine27;
(1b) S-adenosyl-L-methionine + a [histone H3]-N6-methyl-L-lysine27 = S-adenosyl-L-homocysteine + a [histone H3]-N6,N6-dimethyl-L-lysine27
Reaction(KEGG)
Substrate
S-adenosyl-L-methionine [CPD:
C00019 ];
[histone H3]-L-lysine27;
[histone H3]-N6-methyl-L-lysine27
Product
S-adenosyl-L-homocysteine [CPD:
C00021 ];
[histone H3]-N6,N6-dimethyl-L-lysine27;
[histone H3]-N6-methyl-L-lysine27
Comment
This entry describes enzymes that successively methylate the L-lysine27 residue of histone H3 (H3K27) twice, ultimately generating a dimethylated form. These modifications influence the binding of chromatin-associated proteins. The human NSD3 protein also catalyses the activity of EC
2.1.1.370 , [histone H3]-lysine4 N-dimethyltransferase. cf. EC
2.1.1.369 , [histone H3]-lysine27 N-methyltransferase, and EC
2.1.1.356 , [histone H3]-lysine27 N-trimethyltransferase.
History
