Abstract
The synthesis of two enzymes of the arginine catabolic pathway, arginase and ornithine δ-transaminase (OTAse), in Aspergillus nidulans was found to be sensitive to both glucose and ammonium repression. The glucose and nitrogen starvation result in the identical derepression of OTAse synthesis and have no effects on arginase synthesis. Glucose and ammonium affect the kinetics of induction of both enzymes, however, the effect of ammonium is much stronger. Evidence was obtained for the direct involvement of ammonium in the repression phenomenon. The relations between glucose and ammonium repression are discussed.
