Omega-amidase pathway in the degradation of glutamine in Neurospora crassa.
Evidence for the participation of the glutamine transaminase-omega-amidase pathway in the utilization of glutamine in Neurospora crassa was obtained. Its participation is indicated by the in vitro activities of glutamine transaminase and omega-amidase, the in vivo accumulation of alpha-ketoglutaramate when an inhibitor of transamidases is present, and the inhibition by aminooxyacetic acid and 6-diazo-5-oxo-L-norleucine of the ammonium excreted in the presence of glutamine by a mutant strain that lacks glutamate dehydrogenase and glutamate synthase.
