S-adenosyl-L-methionine:[histone H4]-L-lysine20 N6-trimethyltransferase
The enzyme, characterized from the fission yeast Schizosaccharomyces pombe, catalyses three successive methylations of the L-lysine-20 residue of histone H4 (H4K20), forming the trimethylated form. The methylation of this site is apparently not involved in the regulation of gene expression or heterochromatin function but participates in DNA damage response. cf. EC 2.1.1.361, [histone H4]-lysine20 N-methyltransferase, and EC 2.1.1.362, [histone H4]-N-methyl-L-lysine20 N-methyltransferase.
