The pattern of cross-pathway regulation of the arginine synthetic enzyme ornithine carbamoyltransferase was investigated in Neurospora crassa, using single and double mutant auxotrophic strains starved for their required amino acids. These experiments show that starvation for histidine, tryptophan, isoleucine, valine or arginine can result in derepression of ornithine carbamoyltransferase. Methionine starvation also gave slight derepression, but starvation for lysine or leucine gave little or no effect.
利用对所需氨基酸饥饿的单突变和双突变营养缺陷型菌株,研究了粗糙脉孢菌中精氨酸合成酶鸟氨酸氨甲酰转移酶的交叉途径调控模式。这些实验表明,组氨酸、色氨酸、异亮氨酸、缬氨酸或精氨酸饥饿可导致鸟氨酸氨甲酰转移酶的去阻遏。甲硫氨酸饥饿也会导致轻微的去阻遏,但赖氨酸或亮氨酸饥饿几乎没有影响或没有影响。
