Reaction: S-(2E,6E)-farnesyl-L-cysteine + O2 + H2O = (2E,6E)-farnesal + L-cysteine + H2O2
Other name(s): FC lyase; FCLY
Systematic name: S-(2E,6E)-farnesyl-L-cysteine oxidase
Comments: A flavoprotein (FAD). In contrast to mammalian EC 22.214.171.124 (prenylcysteine oxidase) the farnesylcysteine lyase from Arabidopsis is specific for S-farnesyl-L-cysteine and shows no activity with S-geranylgeranyl-L-cysteine.
