Function
function
Catalyzes the reduction of the C14-unsaturated bond of lanosterol, as part of the metabolic pathway leading to cholesterol biosynthesis.
Catalytic activity
- 4,4-dimethyl-5alpha-cholesta-8,24-dien-3beta-ol + NADP+ = 4,4-dimethyl-5alpha-cholesta-8,14,24-trien-3beta-ol + NADPH + H+
- 4,4-dimethyl-8,14-cholestadien-3beta-ol + NADPH + H+ = 4,4-dimethyl-5alpha-cholest-8-en-3beta-ol + NADP+
- 5alpha-cholest-8,14-dien-3beta-ol + NADPH + H+ = 5alpha-cholest-8-en-3beta-ol + NADP+
Pathway
Steroid biosynthesis; cholesterol biosynthesis.
