The family of cytochrome b 5-like proteins includes (besides cytochrome b 5 itself) hemoprotein domains covalently associated with other redox domains in flavocytochrome cytochrome b 2 (L-lactate dehydrogenase; EC 1.1.2.3), sulfite oxidase (EC 1.8.3.1), plant and fungal nitrate reductases (EC 1.7.1.1, EC 1.7.1.2, EC 1.7.1.3), and plant and ...
Cytochrome b5, form A (gene name CYB5A), is a human microsomal cytochrome b5. [5] Cytochrome b5 is a membrane bound hemoprotein which functions as an electron carrier for several membrane bound oxygenases. It has two isoforms produced by alternative splicing. Isoform 1 is bound to the cytoplasmic side of the endoplasmic reticulum. It has a C ...
Cytochrome b5 reductase is a prevalent topic in research and clinical tests to understand the additional functions of the enzyme in other metabolic pathways in the body. Mice and flies are common model organisms used to test for the relationship of cytochrome b5 reductase with the overall health of living organisms.
The protein encoded by the CYB5R3 gene is cytochrome b5 reductase, a flavoprotein that is produced as two different isoforms with different localizations. There is an amphipathic microsomal isoform that is found in all cell types but red blood cells; this isoform has one hydrophobic membrane-anchoring domain and one catalytic domain that is ...
Cytochrome b5 deficiency; ... Cytochrome b 5 deficiency is a rare condition and form of isolated 17,20-lyase deficiency caused by deficiency in cytochrome b 5, ...
Cytochrome b is a protein found in the membranes of aerobic cells. In eukaryotic mitochondria (inner membrane) and in aerobic prokaryotes , cytochrome b is a component of respiratory chain complex III ( EC 1.10.2.2 ) — also known as the bc1 complex or ubiquinol-cytochrome c reductase.
NADH-cytochrome b5 reductase 1 is an enzyme that in humans is encoded by the CYB5R1 gene. [5] [6] [7] Structure. The CYB5R1 gene is located on the 1st chromosome ...
Complex IV contains a cytochrome a/a3-domain that transfers electrons and catalyzes the reaction of oxygen to water. Photosystem II, the first protein complex in the light-dependent reactions of oxygenic photosynthesis, contains a cytochrome b subunit. Cyclooxygenase 2, an enzyme involved in inflammation, is a cytochrome b protein.
