| Research Abstract |
In order to elucidate the function of 6 genes responding to stresses that induce glutamate overproduction in Corynebacterium glutamicum, genetic analyses were conducted. It was found that the disruption of two genes could enhance the growth and the glutamate production under biotin-limiting condition or Tween40-adding condition, respectively, while the disruption of another one gene could reduce the the growth and the glutamate production under penicillinG-adding condition. In order to judge whether a stress-responsive promoter is located in the upstream region of the 6 genes or not, promoter assay systems using GFP or RFP as a reporter were constructed. With these systems, we are making efforts to determine the promoter sequence responding to stresses that induce glutamate overproduction.
