Reaction(IUBMB)
S-adenosyl-L-methionine + a [histone H3]-L-lysine27 = S-adenosyl-L-homocysteine + a [histone H3]-N6-methyl-L-lysine27
Reaction(KEGG)
Substrate
S-adenosyl-L-methionine [CPD:
C00019 ];
[histone H3]-L-lysine27
Product
S-adenosyl-L-homocysteine [CPD:
C00021 ];
[histone H3]-N6-methyl-L-lysine27
Comment
This entry describes enzymes that methylate the L-lysine-27 residue of histone H3 only once, generating a monomethylated form. This modification influences the binding of chromatin-associated proteins. The methylation of lysine-27 leads to transcriptional repression of the affected target genes. cf. EC
2.1.1.371 , [histone H3]-lysine27 N-dimethyltransferase, and EC
2.1.1.356 , [histone H3]-lysine27 N-trimethyltransferase.
History
