Biosynthesis of nonactin from acetate, propionate, and succinate: the assignment of its carbon-13 n.m.r. spectrum by two-dimensional correlation spectroscopy
Abstract
Two-dimensional correlation spectroscopy is used to assign unambiguously the carbon-13 n.m.r. spectrum of nonactin, and studies with 13C labelled acetate, propionate, and succinate have prompted a revision of its mode of biosynthesis in Streptomyces griseus.
