Growth of Neurospora crassa on media containing NH4+ leads to the repression of a variety of permeases and alternative pathways which would generate NH4+, so called "ammonium repression." The mutant am2 which lacks NADP-GDH is not subject to ammonium repression of nitrate reductase or urea permease,
We have studied the changes in the activities of both nitrogenase ("switch off") and glutamine synthetase in Rhodospirillum rubrum upon addition of ammonium ions or glutamine to nitrogen fixing cultures. Both activities decrease drastically and return in a parallel manner when added ammonia is metab
## Abstract In __S. noursei__ JA 3890b which produces nourseothricin, a streptothricinβtype antibiotic, the participation of the glutamine synthetase/glutamate synthase pathway in the regeneration of glutamic acid was established. Glutamate synthase of this organism requires 2βketoglutarate, gluta
## Abstract Growth and urea regulation of heterocyst and nitrogenase formation have been studied in the diazotrophic cyanobacterium __Anabaena cycadeae__ and its glutamine auxotrophic mutant strain lacking glutamine synthetase (GS) activity. The parent strain having normal GS activity utilized urea
An amber mutation (glnA3711), the first nonsense mutation isolated in Klebsiella aerogenes, is described. When amber suppressors were present, the mutant made active glutamine synthetase which was more thermolabile than wild type, showing that glnA3711 lies in the structural gene for glutamine synth
