Characterization of glutamine synthetase from the ammonium-excreting strain HM053 of Azospirillum brasilense
Braz. j. biol; 82 (), 2022
Glutamine synthetase (GS), encoded by glnA, catalyzes the conversion of L-glutamate and ammonium to L-glutamine. This ATP hydrolysis driven process is the main nitrogen assimilation pathway in the nitrogen-fixing bacterium Azospirillum brasilense. The A. brasilense strain HM053 has poor GS activity and l...
