 47-176 1.77e-24

Cytochrome b-561 / ferric reductase transmembrane domain; 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.

Eukaryotic cytochrome b(561), including the CYB561D2 gene product; Cytochrome b(561), as found in eukaryotes, similar to and including the human CYB561D2 gene product. CYB561D2 is a candidate tumor suppressor. The protein might act as a ferric-chelate reductase, catalyzing the reduction of Fe(3+) to Fe(2+), such as associated with the transport of iron from the endosome to the cytoplasm. It is assumed that this protein uses ascorbate as the electron donor. Belongs to the cytochrome b(561) family, which are secretory vesicle-specific electron transport proteins. Cytochromes b(561) are integral membrane proteins that bind two heme groups non-covalently, and may have six alpha-helical trans-membrane segments.

 47-181 4.00e-03

Plant cytochrome b(561), including the carbon monoxide oxygenase ACYB-1; Cytochrome b(561), as found in plants, similar to the Arabidopsis thaliana ACYB-1 gene product, a cytochrome b561 isoform localized to the tonoplast. This protein might act as a ferric-chelate reductase, catalyzing the reduction of Fe(3+) to Fe(2+), and might be capable of trans-membrane electron transport from intracellular ascorbate to extracellular ferric chelates. It is assumed that this protein uses ascorbate as the electron donor. Belongs to the cytochrome b(561) family, which are secretory vesicle-specific electron transport proteins. Cytochromes b(561) are integral membrane proteins that bind two heme groups non-covalently, and may have six alpha-helical trans-membrane segments.
