Nicotinamide adenine dinucleotide phosphate (reduced form)-nitrate reductase was freed from ammonium repression in a Neurospora crassa mutant having drastically lowered glutamine synthetase activity, gln-1a. The general phenomenon of nitrogen metabolite repression required glutamine or some aspect of glutamine metabolism.
烟酰胺腺嘌呤二核苷酸磷酸(还原型)-硝酸还原酶在谷氨酰胺合成酶活性大幅降低的粗糙脉孢菌突变体gln-1a中摆脱了铵阻遏。氮代谢物阻遏的普遍现象需要谷氨酰胺或谷氨酰胺代谢的某些方面。
