In Neurospora crassa, the starvation of tryptophan mutants for tryptophan resulted in the derepression of tryptophan, histidine, and arginine biosynthetic enzymes. This tryptophan-mediated derepression of histidine and arginine biosynthetic enzymes occurred despite the fact that the tryptophan-starved cells had a higher intracellular concentration of histidine and arginine than did nonstarved cells.
在粗糙脉孢菌中,色氨酸突变体缺乏色氨酸会导致色氨酸、组氨酸和精氨酸生物合成酶的去阻遏。尽管色氨酸饥饿的细胞比未饥饿的细胞具有更高的细胞内组氨酸和精氨酸浓度,但色氨酸仍介导了组氨酸和精氨酸生物合成酶的去阻遏。
