2.1.1.361 3 S-adenosyl-L-methionine + a [histone H4]-L-lysine20 - 2.1.1.361 additional information enzyme binding to the nucleosome protects it from degradation during the cell cycle. Full length enzyme has 3.8% of its histone methyltransferase activity on nucleosomes containing the H2A/E61A/ E64A/D90A/E92A mutations compared to wild type nucleosomes 2.1.1.361 additional information the enzyme is completely inactive toward histone H4 with a K20L mutation 2.1.1.361 additional information the proteolytic degradation of the enzyme is controlled by the SCFSlimb ligase complex 2.1.1.361 S-adenosyl-L-methionine + a [histone H4]-L-lysine20 - 2.1.1.361 S-adenosyl-L-methionine + a [histone H4]-L-lysine20 highly specific substrate 2.1.1.361 S-adenosyl-L-methionine + a [histone H4]-N6,N6-dimethyl-L-lysine20 - 2.1.1.361 S-adenosyl-L-methionine + a [histone H4]-N6-methyl-L-lysine20 - 2.1.1.361 S-adenosyl-L-methionine + [p53]-L-lysine382 -
