histone H3K9me2/H3K9me3 demethylase activity [GO_0140684]

Catalysis of the removal of a methyl group from a tri or a dimethyl-lysine residue at position 9 of the histone H3 protein. This is a dioxygenase reaction that is dependent on Fe(II) and 2-oxoglutarate.

histone H3K9me2/H3K9me3 demethylase activity

ID: GO_0140684

Class

Catalysis of the removal of a methyl group from a tri or a dimethyl-lysine residue at position 9 of the histone H3 protein. This is a dioxygenase reaction that is dependent on Fe(II) and 2-oxoglutarate.

Comment: Note that the residue position corresponds to the canonical human H3 histone (UniProtKB:P84243); this residue is conserved across all eukaryotes. Residue 1 is the first residue following removal of the initiating Methionine (Met). Note that each histone is encoded by multiple genes, and sequences may vary across different genes within an organism.
