Cytochrome b-561 recycles ascorbate for the generation of norepinephrine by dopamine-beta-hydroxylase in the chromaffin vesicles of the adrenal gland. It is a transmembrane heme protein with the two heme groups being bound to conserved histidine residues. A cytochrome b-561 homologue, termed Dcytb, is an iron-regulated ferric reductase in the duodenal mucosa. Other homologues of these are also likely to be ferric reductases. SDR2 is proposed to be important in regulating the metabolism of iron in the onset of neurodegenerative disorders.

This model describes a family of cytochrome b proteins which appear to be specific for nickel-iron hydrogenase complexes. Every genome which contains a member of this family posesses a Ni/Fe hydrogenase according to Genome Properties (GenProp0177), and most are gene clustered with other hydrogenase components. Some Ni/Fe hydrogenase-containing species lack a member of this family but contain other CytB homologs (pfam01292) which may substitute for it.
