Outline of Final Research Achievements

We have studied the reaction mechanism and X-ray crystal structure of FAD-dependent monooxygenase QhpG that is involved in the cofactor biogenesis of bactral quinohemoprotein amine dehydrogenase. Our final aim is application of QhpG for a novel tool for peptide engineering. In vitro reaction system for QhpG provided the important information for the chemical structure of the QhpG reaction product. On the basis of X-ray crystal structure of QhpG, we have elucidated the QhpG reaction mechanism including the recognition of the specific Trp residue on the substrate peptide.
