at an initial concentration of added nh4+ of 1 microm , the glutamine synthetase-glutamate synthase pathway represented the major pathway in both bacteria on the basis of the effects of inhibitors of that pathway ( l-methionine-dl-sulfoximine and azaserine ) and of transamination ( aminooxy-acetate ) and the observation that the specific activity of glutamine was greater initially than that of any other amino acid likely to be the first product of an assimilation pathway .
