ENZYME entry: EC

Accepted Name
[Histone H3]-trimethyl-L-lysine(36) demethylase.
Reaction catalysed
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, cf. EC
