In enzymology, an isopiperitenone Delta-isomerase (EC 220.127.116.11) is an enzyme that catalyzes the chemical reaction
- isopiperitenone piperitenone
Hence, this enzyme has one substrate, isopiperitenone, and one product, piperitenone.
This enzyme belongs to the family of isomerases, specifically those intramolecular oxidoreductases transposing C=C bonds. The systematic name of this enzyme class is isopiperitenone Delta8-Delta4-isomerase.
