General Information
Term transmembrane ascorbate ferrireductase activity ID (Ontology) GO:0140571 (Gene Ontology)
Definition Oxidation of Fe(3+) to Fe(2+) on the outer side of a membrane coupled to the reduction of L-ascorbate to monodehydro-L-ascorbate radical on the inner side of a membrane. Electrons get transferred across the membrane during the reaction.[ PubMed:16911521 PubMed:24449903 ]
Also Known As"ascorbate-cytochrome b5 reductase activity" ; "L-ascorbate-cytochrome-b5 reductase activity" ; "L-ascorbate:ferricytochrome-b5 oxidoreductase activity"
