Abstract

In the presence of purified Escherichia coli lysyl-tRNA synthetase [L-lysine:tRNALys ligase (AMP-forming) EC 6.1.1.6], L-lysine, and ATP, addition of the nucleotide ppGpp results in formation of a unique product-A(5')ppp(5') Gpp. The same compound is also formed very rapidly in a cell-free protein-synthesizing system when ppGpp is added. The possible significance of this reaction in the rapid turnover of ppGpp and as a more general mechanism by which an AMP residue is activated and introduced onto a 5'-diphosphorylated species, including the 5'-end of an RNA, is further discussed.

摘要

在纯化的大肠杆菌赖氨酰 - tRNA合成酶[L - 赖氨酸:tRNALys连接酶(形成AMP),EC 6.1.1.6]、L - 赖氨酸和ATP存在的情况下,添加核苷酸ppGpp会导致形成一种独特的产物——A(5')ppp(5')Gpp。当添加ppGpp时,在无细胞蛋白质合成系统中也会非常迅速地形成相同的化合物。本文进一步讨论了该反应在ppGpp快速周转中的可能意义,以及作为一种更普遍的机制,通过该机制AMP残基被激活并引入到5'-二磷酸化的物种上,包括RNA的5'-末端。
