Ascorbate ferrireductase (transmembrane) (EC 1.16.5.1 cytochrome b561) is an enzyme with system name Fe(III):ascorbate oxidorectuctase (electron-translocating). This enzyme catalyses the following chemical reaction ascorbate [side 1] + Fe(III) [side 2] monodehydroascorbate [side 1] + Fe(II) [side 2]Ascorbate ferrireductase is a diheme cytochrome that acts on hexacyanoferrate(III) and other ferric chelates.
