摘要
Incorporation studies, using intact cells of Aspergillus melleus and deuterium labelled precursors in association with H-2 NMR spectroscopy as method of analysis, have shown that the enzyme-bound intermediates generated in the first two steps of the chain extension cycle catalysed by the aspyrone polyketide synthase (PKS) are thioesters of acetoacetic acid and (R)-3-hydroxybutyric acid.
