Comment
This entry describes enzymes that successively methylate the L-lysine27 residue of histone H3 (H3K27), ultimately generating a trimethylated form. These modifications influence the binding of chromatin-associated proteins. The methylation of lysine27 leads to transcriptional repression of the affected target genes. The enzyme associates with other proteins to form a complex that is essential for activity. The enzyme can also methylate some non-histone proteins. cf. EC 2.1.1.369, [histone H3]-lysine27 N-methyltransferase and EC 2.1.1.371, [histone H3]-lysine27 N-dimethyltransferase.
