A multimeric ketolactonizing enzyme system has been purified 10-fold from (+)-camphor-grown Pseudomonas putida, and contains flavin mononucleotide and flavin adenine dinucleotide. Electron transport in the system is tightly controlled and unitary stoichiometry of reactants and products has been shown. A kinetic assay for the reaction has been developed, and the reversible reduction of flavin during catalysis was investigated.
