Mixed function oxidases, classification

These light-producing oxidations are quite different reactions in each of the three most thoroughly studied organisms, Cypridina, bacteria, and fireflies (382,566,567,569,709,761). The structures of the two luciferins, LHk and LHjf, and of their oxidation products (oxyluciferins , 568), and the fate of the long-chain fatty aldehyde which acts as cofactor in bacterial luminescent oxidation of FMNH, are all unknown. Each luminescent system requires molecular oxj en and a potential source of electrons, in common with mixed function oxidases, but the significance of these characteristics in terms of oxidase classification remains to be determined.
