Abstract

Summary: wild-type is almost unable to grow on glutamine as sole nitrogen and carbon source but a GDH; GS double mutant strain, lacking NADP-dependent glutamate dehydrogenase and partially lacking glutamine synthetase did grow. Under these conditions, the double mutant had a higher chemical energy content than the wild-type. Enzyme assays and labelling experiments with glutamine indicated that in the double mutant glutamine was degraded to ammonium and to carbon skeletons by glutamate synthase, the catabolic (NADH-dependent) glutamate dehydrogenase and the glutamine transaminase-ω-amidase pathway.
