ID 1.14.11.68 DE [histone H3]-trimethyl-L-lysine(27) demethylase. CA 2 2-oxoglutarate + N(6),N(6),N(6)-trimethyl-L-lysyl(27)-[histone H3] + CA 2 O2 = 2 CO2 + 2 formaldehyde + N(6)-methyl-L-lysyl(27)-[histone H3] + CA 2 succinate. CC -!- Requires iron(II). CC -!- This entry describes a group of enzymes that demethylate N-methylated CC L-lysine residues at position 27 of histone H3 (H3K27). CC -!- The enzymes are dioxygenases and act by hydroxylating the methyl CC group, forming an unstable hemiaminal that leaves as formaldehyde. CC -!- They can act on tri- and di-methylated forms, but have no activity CC with the mono-methylated form.
