The biosynthesis of lovastatin in A. terreus is under the control of two major positive regulators, the LovE pathway-specific regulator and LaeA global regulator of the secondary metabolism of fungi. It is shown that laeA expression can be negatively regulated by LovE, the Zn Cys transcription factor of lovastatin biosynthesis. The overexpression of lovE under the control of the 2 6 gpdA constitutive promoter from Aspergillus nidulans, which results in a 10- to 30-fold increase in lovastatin production is http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Applied Biochemistry and Microbiology Springer Journals
