RNA extracted from growing Escherichia coli can direct the in vitro synthesis of ribosomal proteins L12 and L10 and elongation factor Tu when an E. coli system is used. The synthesized L12 can be bound to L12-depleted ribosomes and the synthesized elongation factor Tu can form complexes with both elongation factor Ts and GDP. Guanosine 5'-diphosphate 3'-diphosphate has no effect on the synthesis of these proteins from an RNA template but inhibits their synthesis when a DNA template is used.
当使用大肠杆菌系统时,从生长中的大肠杆菌中提取的RNA能够指导核糖体蛋白L12和L10以及延伸因子Tu的体外合成。合成的L12可以与缺乏L12的核糖体结合,合成的延伸因子Tu可以与延伸因子Ts和GDP形成复合物。5'-二磷酸鸟苷3'-二磷酸对从RNA模板合成这些蛋白质没有影响,但当使用DNA模板时会抑制它们的合成。
