WebFeb 8, 2013 · fkbO is a homologue of rapK encoding chorismatase related to the biosynthesis of starter unit DHCHC from chorismate in the rapamycin biosynthetic gene cluster. FkbO and RapK are good targets for mutational biosynthesis to produce novel analogues of tacrolimus, ascomycin, and rapamycin, which could be important drugs for … WebMar 2, 2013 · A mechanism for FkbO is proposed based on both interactions between the inhibitor and the surrounding amino acids and an FkbO structure with chorismate modelled in the active site. We suggest that the methylene group of the chorismate enol ether takes up a proton from an active-site glutamic acid residue, thereby initiating chorismate … WebNov 5, 2024 · PDF download and online access $59.00 Details Check out Abstract The FkbO and Hyg5 subfamilies of chorismatases share the same active-site architectures, … how do cofactors influence enzyme activity
