Cholesterol Side-Chain Cleavage Enzyme, Mitochondrial

**Semantic type:** Amino Acid, Peptide, or Protein|Enzyme

**Definition:** Cholesterol side-chain cleavage enzyme, mitochondrial (521 aa, ~60 kDa) is encoded by the human CYP11A1 gene. This protein plays a role in the catalysis of the side-chain cleavage reaction converting cholesterol to pregnenolone.
