Popis: | The crystal structure of CYP105D18 and its unique structural features for papaverine N-oxidation are presented. The bacterial CYP105 family is involved in secondary metabolite biosynthetic pathways and plays essential roles in the biotransformation of xenobiotics. This study investigates the newly identified H2O2-mediated CYP105D18 from Streptomyces laurentii as the first bacterial CYP for N-oxidation. The catalytic efficiency of CYP105D18 for papaverine N-oxidation was 1.43 s−1 µM −1. The heme oxidation rate (k) was low ( |
