Prenylcysteine oxidase

In enzymology, a prenylcysteine oxidase is an enzyme that catalyzes the chemical reaction


 * an S-prenyl- L -cysteine + O2 + H2O $$\rightleftharpoons$$ a prenal + L -cysteine + H2O2

The 3 substrates of this enzyme are S-prenyl- L -cysteine, O2, and H2O, whereas its 3 products are prenal, L -cysteine, and H2O2.

This enzyme belongs to the family of oxidoreductases, specifically those acting on a sulfur group of donors with oxygen as acceptor. The systematic name of this enzyme class is S-prenyl-L-cysteine:oxygen oxidoreductase. This enzyme is also called prenylcysteine lyase.
