title: Studies on the biosynthesis of terrecyclic acid A, an antitumor antibiotic from Aspergillus terreus.
abstract: The biosynthesis of terrecyclic acid A was investigated using 13C-labeled acetates and mevalonate. 13C NMR spectral analysis of isolated labeled terrecyclic acid demonstrated that the structure is assembled via an isoprene pathway.
