ID 2.1.1.360 DE [histone H3]-lysine(79) N-trimethyltransferase. CA L-lysyl(79)-[histone H3] + 3 S-adenosyl-L-methionine = N(6),N(6),N(6)- CA trimethyl-L-lysyl(79)-[histone H3] + 3 S-adenosyl-L-homocysteine + CA 3 H(+). CC -!- The enzyme successively methylates the L-lysine(79) residue of CC histone H3 (H3K79), ultimately generating a trimethylated form. CC -!- These modifications influence the binding of chromatin-associated CC proteins. CC -!- This is the only known methylation event of a lysine residue within CC the core region of a histone, as all other such modifications occur CC at the tail.
