General Information

EC Number General Information Comment Organism
1.6.2.2 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
1.6.2.2 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
