Glutamine Metabolism in Nitrogen-starved Conidia of Neurospora crassa EspĂ­n, Guadalupe and Palacios, Rafael and Mora, Jaime,, 115, 59-68 (1979), doi = https://doi.org/10.1099/00221287-115-1-59, publicationName = Microbiology Society, issn = 1350-0872, abstract= During nitrogen deprivation, de novo synthesis of glutamine synthetase was induced in non-growing conidia of Neurospora crassa. When ammonia or glutamine was added to conidia which had been deprived of nitrogen, glutamine and arginine accumulated at a higher rate than in condia not deprived of nitrogen. The degradation of exogenous glutamine to glutamate is apparently a necessary step in the accumulation of glutamine and arginine within the conidia. In non-growing conidia, a cycle probably operates in which glutamine is degraded and resynthesized. The advantages of such a cycle would be that the carbon and nitrogen could be used to synthesize amino acids in general, as well as for the synthesis and accumulation of arginine and/or glutamine in particular., language=, type=
