General Information
Term histone H3K27 methyltransferase activity ID (Ontology) GO:0046976 (Gene Ontology)
Definition Catalysis of the reaction: S-adenosyl-L-methionine + histone H3 L-lysine (position 27) = S-adenosyl-L-homocysteine + histone H3 N6-methyl-L-lysine (position 27). This reaction is the addition of a methyl group to the lysine residue at position 27 of the histone H3 protein.
Also Known As "histone H3K27 methylase activity" ; "histone lysine N-methyltransferase activity (H3-K27 specific)" ; "histone methylase activity (H3-K27 specific)" (for all, see Synonyms field below)
