Abstract
Leucine transfer ribonucleic acid (tRNA) was almost fully charged, and the isoleucine-valine and leucine enzymes remained derepressed when trifluoroleucine was added to a leucine auxotroph. High levels of charged leucine tRNA and derepression were also found in a leucyl-tRNA synthetase mutant.
摘要
将三氟亮氨酸添加到亮氨酸营养缺陷型菌株中时，亮氨酰转运核糖核酸（tRNA）几乎完全被氨酰化，而异亮氨酸 - 缬氨酸和亮氨酸相关的酶仍处于去阻遏状态。在亮氨酰 - tRNA合成酶突变体中也发现了高水平的氨酰化亮氨酸tRNA和去阻遏现象。
