Systematic name
[histone H3]-N6,N6-dimethyl-L-lysine9,2-oxoglutarate:oxygen oxidoreductase
Comment
Requires iron(II). This entry describes a group of enzymes that demethylate N-methylated Lys-9 residues in the tail of the histone protein H3 (H3K9). This lysine residue can exist in three methylation states (mono-, di- and trimethylated), but this group of enzymes only act on the the di- and mono-methylated forms. The enzymes are dioxygenases and act by hydroxylating the methyl group, forming an unstable hemiaminal that leaves as formaldehyde. cf. EC 1.14.11.66, [histone H3]-trimethyl-L-lysine9 demethylase.
