Moenomycin Biosynthesis: Structure and Mechanism of Action of the Prenyltransferase MoeN5. Angew.Chem.Int.Ed.Engl., 55:4716-4720, 2016 Cited by PubMed Abstract: The structure of MoeN5, a unique prenyltransferase involved in the biosynthesis of the antibiotic moenomycin, is reported. MoeN5 catalyzes the reaction of geranyl diphosphate (GPP) with the cis-farnesyl group in phosphoglycolipid 5 to form the (C25) moenocinyl-sidechain-containing lipid 7. GPP binds to an allylic site (S1) and aligns well with known S1 inhibitors. Alkyl glycosides, glycolipids, can bind to both S1 and a second site, S2. Long sidechains in S2 are "bent" and co-locate with the homoallylic substrate isopentenyl diphosphate in other prenyltransferases. These observations support a MoeN5 mechanism in which 5 binds to S2 with its C6-C11 group poised to attack C1 in GPP to form the moenocinyl sidechain, with the more distal regions of 5 aligning with the distal glucose in decyl maltoside. The results are of general interest because they provide the first structures of MoeN5 and a structural basis for its mechanism of action, results that will facilitate the design of new antibiotics.
