In enzymology, a cholestenol Δ-isomerase (EC 5.3.3.5) is an enzyme that catalyzes the chemical reaction
- 5alpha-cholest-7-en-3beta-ol 5alpha-cholest-8-en-3beta-ol
Hence, this enzyme has one substrate, 5alpha-cholest-7-en-3beta-ol, and one product, 5alpha-cholest-8-en-3beta-ol.
This enzyme belongs to the family of isomerases, specifically those intramolecular oxidoreductases transposing C=C bonds. The systematic name of this enzyme class is Delta7-cholestenol Delta7-Delta8-isomerase. This enzyme participates in biosynthesis of steroids.
