(1b) a [histone H3]-N6,N6-dimethyl-L-lysine36 + 2-oxoglutarate + O2 = a [histone H3]-N6-methyl-L-lysine36 + succinate + formaldehyde + CO2
Systematic Name
[histone H3]-N6,N6,N6-trimethyl-L-lysine36,2-oxoglutarate:oxygen oxidoreductase
Function
Requires iron(II). This entry describes a group of enzymes that demethylate N-methylated Lys36 residues in the tail of the histone protein H3 (H3K36). This lysine residue can exist in three methylation states (mono-, di- and trimethylated), but this group of enzymes only act on the the tri- and di-methylated forms. The enzymes are dioxygenases and act by hydroxylating the methyl group, forming an unstable hemiaminal that leaves as formaldehyde. Since trimethylation of H3K36 enhances transcription, this enzyme acts as a transcription repressor. The enzymes that possess this activity often also catalyse the activity of EC 1.14.11.66, [histone H3]-trimethyl-L-lysine9 demethylase. cf. EC 1.14.11.27, [histone H3]-dimethyl-L-lysine36 demethylase.
