Identification of a major cis-acting DNA element controlling the bidirectionally transcribed penicillin biosynthesis genes acvA (pcbAB) and ipnA (pcbC) of Aspergillus nidulans.

Abstract excerpt

The beta-lactam antibiotic penicillin is produced as a secondary metabolite by some filamentous fungi. In this study, the molecular regulation of the Aspergillus (Emericella) nidulans penicillin biosynthesis genes acvA (pcbAB) and ipnA (pcbC) was analyzed. acvA and ipnA are divergently oriented and separated by an intergenic region of 872 bp. Translational fusions of acvA and ipnA with the two Escherichia coli...
