Outline of Final Research Achievements |
The multifunctional cytochrome P450 enzyme RosC catalyzes a two-step, hydroxylation and alcohol oxidation, oxidation reaction to form the C-20 formyl group in the biosynthesis of a 16-membered macrolide antibiotic rosamicin produced by Micromonospora rosaria IFO13697. In this study, we confirmed that RosC has another oxidation activity, which a formyl group at C-20 of rosamicin is converted into a carboxyl group. Moreover, random mutation analysis was also performed for rosC gene using error-prone PCR, and Leucine-176 of RosC is one of amino acid residue controlling of oxidation reaction.
