Askorbat ferireduktaza (transmembranska) (EC 1.16.5.1, citohrom b561 (nespecifična)) je enzim sa sistematskim imenom Fe(III):askorbatna oksidorektuktaza (translokacija elektrona).[1][2][3][4][5][6] Ovaj enzim katalizuje sledeću hemijsku reakciju
- askorbat [strana 1] + Fe(III) [strana 2] monodehidroaskorbat [strana 1] + Fe(II) [strana 2]
Ovaj dihemni citohrom transportuje elektrone kroz membrane, kao što je spoljašnja membrana enterocita.
