【 摘 要 】

RNase P and ribosomes must interact with similar substrate molecules, tRNA precursors in the case of RNase P and aminoacyl-, peptidyl- or free tRNAs in the case of ribosomes. In order to compare the substrate recognition mechanisms between ribosomes and RNase P, protein synthesis inhibitors have been assayed for their effect on the catalytic activity of the RNA component of Escherichia coli RNase P (M1 RNA). Puromycin has an inhibitory effect that could be related to similar substrate recognition mechanisms by rRNA in the ribosome and by M1 RNA in RNase P.
