EC 2.1.1.357

Accepted name: histone H3 lysine36 N-dimethyltransferase

Reaction: 2 S-adenosyl-L-methionine + a [histone H3]-L-lysine36 = 2 S-adenosyl-L-homocysteine + a [histone H3]-N6,N6-dimethyl-L-lysine36 (overall reaction)
(1a) S-adenosyl-L-methionine + a [histone H3]-L-lysine36 = S-adenosyl-L-homocysteine + a [histone H3]-N6-methyl-L-lysine36
(1b) S-adenosyl-L-methionine + a [histone H3]-N6-methyl-L-lysine36 = S-adenosyl-L-homocysteine + a [histone H3]-N6,N6-dimethyl-L-lysine36

Other name(s): KMT3B (gene name); KMT3C (gene name); NSD2 (gene name); NSD3 (gene name); SETMAR (gene name); WHSC1 (gene name)

Systematic name: S-adenosyl-L-methionine:[histone H3]-L-lysine36 N6-dimethyltransferase

Comments: This entry describes a group of metazoan enzymes that catalyse two successive methylations of lysine 36 of histone H3 (H3K36), forming mono- and dimethylated forms. These modifications influence the binding of chromatin-associated proteins. The product can be further methylated to the trimethyl form by EC 2.1.1.358, histone H3 dimethyl-L-lysine36 N-methyltransferase. The yeast SET2 enzyme can catalyse all three methylations (see EC 2.1.1.359, histone H3 lysine36 N-trimethyltransferase).
