Fig. 3. Roles of ApmA and ApmB in the biosynthesis of asperphenamate. ApmA and/or ApmB were expressed in A. nidulans. (A) HPLC analysis of metabolites produced from ApmA-expressing strains with feeding of precursors 4 and 5. (B) HPLC analysis of metabolites produced from ApmB-expressing strains with feeding of precursors 3, 4 and 5. (C) 1 was obtained by co-expressions of ApmA and ApmB.
