General Information
Term histone H3K9 trimethyltransferase activity ID (Ontology) GO:0140949 (Gene Ontology)
Definition Catalysis of the reaction: L-lysyl9-[histone H3] + 3 S-adenosyl-L-methionine = 3 H+ + N6,N6,N6-trimethyl-L-lysyl9-[histone H3] + 3 S-adenosyl-L-homocysteine. This reaction is the successive addition of three methyl groups to the unmethylated lysine residue at position 9 of histone H3, producing histone H3K9me3.
Also Known As "histone H3K9 mono/di/trimethylase activity" ; "histone H3K9 trimethylase activity" ; "histone lysine N-trimethyltransferase activity (H3-K9 specific)"
