IUBMB Enzyme Nomenclature


Accepted name: peptidyl-lysine (3S)-dioxygenase

Reaction: a [protein]-L-lysine + 2-oxoglutarate + O2 = a [protein]-(3S)-3-hydroxy-L-lysine + succinate + CO2

Other name(s): JMJD7 (gene name); Jumonji domain-containing protein 7; JmjC domain-containing protein 7

Systematic name: [protein]-L-lysine,2-oxoglutarate:oxygen oxidoreductase (3S-hydroxylating)

Comments: Requires iron(II). The enzyme acts on specific lysine residues in its substrates, and is stereo-specific. The enzyme encoded by the human JMJD7 gene acts specifically on two related members of the translation factor family of GTPases, DRG1 and DRG2.
