Cytochrome b reductase
WebDuodenal cytochrome B (Dcytb) also known as cytochrome b reductase 1 is an enzyme that in humans is encoded by the CYBRD1 gene . Dcytb CYBRD1 was first identified as a ferric reductase enzyme which catalyzes the reduction of Fe 3+ to Fe 2+ required for dietary iron absorption in the duodenum of mammals.
