Abstract

An analogue of valine in which valine is coupled by its amino group to a chlorinated dihydroisocoumarin moiety inhibits competitively the tRNAVal charging with valine catalyzed by pure yeast valyl-tRNA synthetase. The inhibition constant is much lower for the ATPaiPPi exchange reaction than for the tRNA charging one, indicating different rate-determining steps in the two reactions.

缬氨酸的类似物,其中缬氨酸通过其氨基偶联到氯化的二氢异香豆素片段,竞争性地抑制由纯酵母缬氨酸- trna合成酶催化的与缬氨酸带电的tRNAVal。ATPaiPPi交换反应的抑制常数比tRNA充电反应的抑制常数低得多,这表明两种反应的速率决定步骤不同。
