ID 1.8.3.5 DE prenylcysteine oxidase. AN prenylcysteine lyase. CA an S-prenyl-L-cysteine + H2O + O2 = a prenal + H2O2 + L-cysteine. CC -!- Cleaves the thioether bond of S-prenyl-L-cysteines, such as CC S-farnesylcysteine and S-geranylgeranylcysteine. CC -!- N-Acetyl-prenylcysteine and prenylcysteinyl peptides are not CC substrates. CC -!- May represent the final step in the degradation of prenylated CC proteins in mammalian tissues. CC -!- Formerly EC 4.4.1.18. DR F1N2K1, PCYOX_BOVIN; Q9UHG3, PCYOX_HUMAN; Q95KC9, PCYOX_MACFA; DR Q9CQF9, PCYOX_MOUSE; Q5R748, PCYOX_PONAB; Q99ML5, PCYOX_RAT ; //
