cholesterol oxidase M-CSA #822 | Cholesterol oxidase catalyses the oxidation and isomerisation of cholesterol to form cholest-4-en-3-one using FAD as a cofactor. The two forms of the enzyme found in Brevibacterium BCO1 and BCO2 do not show any structural or sequence homology, despite carrying out the same reaction. As a result their mechanisms are believed to be different. Study of the enzymes that degrade cholesterol is clearly of great relevance to medicine due to the role of the steroid in cardiovascular disease. | Defined by 4 residues: HIS:B-69 [auth B-121]GLU:B-259 [auth B-311]GLU:B-423 [auth B-475]ARG:B-425 [auth B-477] | EC: 1.1.3.6 (PDB Primary Data) |
