Function and Biology Details

Reactions catalysed:
(1a) S-adenosyl-L-methionine + a [histone H3]-L-lysine(4) = S-adenosyl-L-homocysteine + a [histone H3]-N(6)-methyl-L-lysine(4)
(1a) S-adenosyl-L-methionine + a [histone H3]-L-lysine(9) = S-adenosyl-L-homocysteine + a [histone H3]-N(6)-methyl-L-lysine(9)
(1a) S-adenosyl-L-methionine + a [histone H3]-L-lysine(36) = S-adenosyl-L-homocysteine + a [histone H3]-N(6)-methyl-L-lysine(36)
S-adenosyl-L-methionine + a [histone H4]-L-lysine(20) = S-adenosyl-L-homocysteine + a [histone H4]-N(6)-methyl-L-lysine(20)
S-adenosyl-L-methionine + a [histone H4]-N(6)-methyl-L-lysine(20) = S-adenosyl-L-homocysteine + a [histone H4]-N(6),N(6)-dimethyl-L-lysine(20)
