Glutamine auxotrophic (Gln-) and L-methionine D,L-sulfoximine (MSX) resistant (MSXr) mutants of N. muscorum were isolated and characterized for nitrogen nutrition, nitrogenase activity, glutamine synthetase (GS) activity and glutamine amide, alpha-keto-glutarate amido transferase (GOGAT) activity. T
Methylparathion and Benthiocarb inhibition of N2 fixation in the cyanobacterium Nostoc muscorum was reversed by Ca(2+) at 1 mM but not at 0.1 mM. The concentration of intracellular Ca(2+) was relatively high in the presence of these pesticides when 1 mM Ca(2+) was also present, indicating that intra
