Azorhizobium caulinodans PII and GlnK proteins control nitrogen fixation and ammonia assimilation.

Journal of bacteriology - 1 Apr 1999

Michel-Reydellet N, Kaminski P A

Abstract excerpt

We herein report that Azorhizobium caulinodans PII and GlnK are not necessary for glutamine synthetase (GS) adenylylation whereas both proteins are required for complete GS deadenylylation. The disruption of both glnB and glnK resulted in a high level of GS adenylylation under the condition of nitrogen fixation, leading to ammonium excretion in the free-living state. PII and GlnK also controlled nif gene...
