General Information | Comment | Organism |
---|---|---|
additional information | the NADH-cytochrome b5 reductase is a flavoprotein consisting of NADH and FAD binding domains, that catalyzes electron transfer from the two-electron carrier NADH to the one-electron carrier cytochrome b5 | Sus scrofa |
physiological function | the enzyme catalyzes the electron transfer from NADH to cytochrome b5 and participates in fatty acid synthesis, cholesterol synthesis, and xenobiotic oxidation as a member of the electron transport chain on the endoplasmic reticulum. In erythrocytes, the enzyme also participates in the reduction of methemoglobin | Sus scrofa |
