IUBMB Enzyme Nomenclature


Accepted name: 2'-deoxymugineic-acid 2'-dioxygenase

Reaction: 2'-deoxymugineic acid + 2-oxoglutarate + O2 = mugineic acid + succinate + CO2

Other name(s): IDS3

Systematic name: 2'-deoxymugineic acid,2-oxoglutarate:oxygen oxidoreductase (2-hydroxylating)

Comments: Requires iron(II). It is also likely that this enzyme can catalyse the hydroxylation of 3-epihydroxy-2'-deoxymugineic acid to form 3-epihydroxymugineic acid.
