Polyoximic acid biosynthesis
WebFeb 3, 2015 · This chapter describes four-membered heterocyclic rings of azetidine, azetines, oxetanes, and dithiethanes, and their fused derivatives. It deals with biosynthetic studies conducted on the natural polyoxins A, F, H, I, and K, all bearing the four-membered ring of polyoximic acid (POIA). WebThe α-keto acid 50 is transaminated, potentially catalysed by NikT and mediated through an NRPS mechanism involving NikE, to generate 4-(2′-pyridinyl)-homothreonine 51. 98 For polyoxin biosynthesis, the amino acid carbamoylpolyoxamic acid has been shown to be ligated to the nucleoside core by PolG, an ATP-dependent ligase of the ATP grasp ...
