Accepted name: [histone H3]-lysine36 N-trimethyltransferase
Reaction: 3 S-adenosyl-L-methionine + a [histone H3]-L-lysine36 = 3 S-adenosyl-L-homocysteine + a [histone H3]-N6,N6,N6-trimethyl-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
(1c) 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): SET2 (gene name); KMT3A (gene name)
Systematic name: S-adenosyl-L-methionine:[histone H3]-L-lysine36 N6-trimethyltransferase
Comments: The enzyme, characterized from yeast and mammals, catalyses the successive methylation of lysine36 of histone H3 (H3K36), forming the trimethylated form. These modifications influence the binding of chromatin-associated proteins. The enzyme couples the methylation reactions with transcriptional elongation through an interaction with the large subunit of RNA polymerase II. cf. EC, [histone H3]-lysine36 N-dimethyltransferase.
