EC 2.1.1.358

Accepted name: histone H3 dimethyl-L-lysine36 N-methyltransferase

Reaction: S-adenosyl-L-methionine + a [histone H3]-N6,N6-dimethyl-L-lysine36 = S-adenosyl-L-homocysteine + a [histone H3]-N6,N6,N6-trimethyl-L-lysine36

Other name(s): KMT3A (gene name); SETD2 (gene name)

Systematic name: S-adenosyl-L-methionine:[histone H3]-N6,N6-dimethyl-L-lysine36 N6-methyltransferase

Comments: The enzyme, found in metazoa, methylates a dimethylated L-lysine36 residue of histone H3 (H3K36), which has been methylated previously by EC 2.1.1.357, histone H3 lysine36 N-dimethyltransferase. The homologous enzyme from yeast catalyses all three methylations (see EC 2.1.1.359, histone H3 lysine36 N-trimethyltransferase).
