Abstract

Specific 5-S RNA-protein complexes were reconstituted from Escherichia coli 5-S RNA and 50-S ribosomal proteins. These complexes consist of 5-S RNA and two major proteins, namely E-L18 and E-L25. Analysis for enzymatic activities shows that ATP and GTP are hydrolyzed and that this hydrolysis is independent of elongation factors.

摘要

特定的5-S RNA-蛋白质复合物由大肠杆菌5-S RNA和50-S核糖体蛋白重构而成。这些复合物由5-S RNA和两种主要蛋白质组成，即E-L18和E-L25。酶活性分析表明，ATP和GTP会被水解，且这种水解不依赖于延伸因子。
