(5) Regulatory mutations, tightly linked to gabA, were selected by reverting an areAr-2 strain on GABA as nitrogen source.
(6) Surprisingly, we have selected rare intracistronic revertants of areAr-18.
(7) A sensibility index was calculated by dividing the integrated area under the obtained vibrogram curve of each object tested (areaT) by that of the corresponding area under a superimposed and age matched reference curve (areaR).
(8) Mutants at the areA locus (areAr) have also been isolated on the basis of resistance to these analogues, with nitrate or L-aspartate as the nitrogen source.
(9) These, similar to tamAr lesions, result in resistance to methylammonium and are partially repressed for ammonium repressible system, but in contrast to tamAr, areAr alleles have wild-type NADP-GDH activity and normal ammonium efflux.
