oxidoreduction-driven active transmembrane transporter activity oxidoreductase activity, acting on metal ions transmembrane ascorbate ferrireductase activity https://github.com/geneontology/go-ontology/issues/26941 https://github.com/geneontology/go-ontology/issues/30193 L-ascorbate:ferricytochrome-b5 oxidoreductase activity 2020-12-18T16:25:06Z 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. molecular_function EC:7.2.1.3 L-ascorbate-cytochrome-b5 reductase activity RHEA:30403 pg GO:0140571 ascorbate-cytochrome b5 reductase activity MetaCyc:RXN-15598
