|[Histone H3]-trimethyl-L-lysine(36) demethylase.
|A [histone H3]-N(6),N(6),N(6)-trimethyl-L-lysine(36) + 2 2-oxoglutarate + 2 O(2) <=> a [histone H3]-N(6)-methyl-L-lysine(36) + 2 succinate + 2 formaldehyde + 2 CO(2)|
- Requires iron(II).
- This entry describes a group of enzymes that demethylate N-methylated
Lys(36) 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 catalyze the
activity of EC 18.104.22.168, cf. EC 22.214.171.124.
