structural biosynthetic genes encoding enzymes presumed to be involved in the production
of cryptic secondary metabolites. There are five nonribosomal peptide synthetase (NRPS)-
like genes with the predicted AT-TE domain architecture within the A. terreus genome.
Among the five genes, only the product of pgnA remains unknown. The Tet-on system is an
inducible, tunable and metabolism-independent expression system originally developed for …
