Spirocyclase AveC-like AveC catalyzes the stereospecific spiroketalization of a dihydroxy-ketone polyketide intermediate in the biosynthetic pathway of Avermectin, a potent antiparasitic agent. Additionally, it has a unique dehydration activity that serves to determine the regiospecific saturation pattern for spiroketal diversity. MeiC, the counterpart in the biosynthesis of AVE-like meilingmycin, also has spirocyclase activity, but lacks the dehydratase activity. |
