In enzymology a corticosteroid side-chain-isomerase (EC 5.3.1.21) is an enzyme that catalyzes the chemical reaction11-deoxycorticosterone 20-hydroxy-3-oxopregn-4-en-21-alHence this enzyme has one substrate 11-deoxycorticosterone and one product 20-hydroxy-3-oxopregn-4-en-21-al.This enzyme belongs to the family of isomerases specifically those intramolecular oxidoreductases interconverting aldoses and ketoses.
