 3-196 3.82e-43

Cytochrome b (N-terminus)/b6/petB: Cytochrome b is a subunit of cytochrome bc1, an 11-subunit mitochondrial respiratory enzyme. Cytochrome b spans the mitochondrial membrane with 8 transmembrane helices (A-H) in eukaryotes. In plants and cyanobacteria, cytochrome b6 is analogous to eukaryote cytochrome b, containing two chains: helices A-D are encoded by the petB gene and helices E-H are encoded by the petD gene in these organisms. Cytochrome b/b6 contains two bound hemes and two ubiquinol/ubiquinone binding sites. The C-terminal portion of cytochrome b is described in a separate CD.

Non-vertebrate eumetazoan cytochrome b(561); Cytochrome b(561), as found in non-vertebrate eumetazoans, similar to the Drosophila melanogaster CG1275 gene product. This 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.

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.

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.

 5-153 4.42e-23

Vertebrate cytochrome b(561), CYBRD1 gene product; Duodenal cytochrome b or ferric-chelate reductase 3, a cytochrome b(561), as found in vertebrates, which 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. This protein is expressed at the brush border of duodenal enterocytes and may play a role in the uptake of dietary Fe(3+), facilitating its transport into the mucosal cells. It may also be involved in the recycling of extracellular ascorbate in erythrocyte membranes, and act as a ferrireductase in epithelial cells of the respiratory system. 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.
