| def | "Catalysis of the reaction: S-adenosyl-L-methionine + histone H4 L-lysine (position 20) = S-adenosyl-L-homocysteine + histone H4 N6-methyl-L-lysine (position 20). This reaction is the addition of a methyl group onto lysine at position 20 of the histone H4 protein." [PMID:12086618]

|---|
| comment | Note that in some species, the methyl group may be added to a lysine in a slightly different position of the histone H4 protein, but that this term still applies.
