Abstract

A regulatory mutation has been identified that reduces expression of asparaginase II in exponential phase cells of to 25 % or less of the wild-type activity. Mutants in this gene () can be derepressed for asparaginase II by nitrogen starvation and will grow with D-asparagine as the sole nitrogen source. assorts independently from and . Mutation in either of the latter two genes results in lack of asparaginase II activity under any growth conditions.
