Prenylcysteine oxidase

Template:Infobox enzyme In enzymology, a prenylcysteine oxidase (Template:EC number) 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.
