Biosynthesis of averufin in Aspergillus parasiticus from [13C]-acetate
Abstract
The 13C n.m.r. spectrum of averufin has been completely assigned, providing unambiguous proof of its structure; the 13C n.m.r. spectra of averufin enriched with [1-13C]-, [2-13C]-, and [1,2-13C2]-acetate by Aspergillus parasiticus established its formation from ten intact acetate units and the mode of folding of the precursor decaketide chain.
