Sysname
S-adenosyl-L-methionine:[histone H3]-N6,N6-dimethyl-L-lysine9 N6-methyltransferase
Reaction(IUBMB)
S-adenosyl-L-methionine + a [histone H3]-N6,N6-dimethyl-L-lysine9 = S-adenosyl-L-homocysteine + a [histone H3]-N6,N6,N6-trimethyl-L-lysine9
Reaction(KEGG)
Substrate
S-adenosyl-L-methionine [CPD:
C00019 ];
[histone H3]-N6,N6-dimethyl-L-lysine9
Product
S-adenosyl-L-homocysteine [CPD:
C00021 ];
[histone H3]-N6,N6,N6-trimethyl-L-lysine9
Comment
The enzyme methylates only dimethylated lysine9 of histone H3 (H3K9), forming the trimethylated form. This modification influences the binding of chromatin-associated proteins. In general, the methylation of H3K9 leads to transcriptional repression of the affected target genes. The enzyme is highly upregulated in Huntington disease patients. cf. EC
