Flavin-containing monooxygenases in plants: looking beyond detox.
Flavin-containing monooxygenases (FMOs) are known in bacteria, yeast and mammals where they catalyze the transfer of one atom of molecular O(2) to low molecular weight substrates. The predominant physiological function of animal FMOs appears to be detoxification of a vast spectrum of xenobiotics but until recently very little was known about the function of FMOs in plants. In the last two to three years, genetic and biochemical characterization has shown that plant FMOs can catalyze specific steps in the biosynthesis of auxin or in the metabolism of glucosinolates, and, furthermore, have a role in pathogen defence. Thus, plant FMOs hint that further FMO functions might be identified also in non-plant organisms and could stimulate novel research in this area.
