Subsites for substrate recognition by bacterial ribonuclease P.
We have prepared series of shape variant RNAs of a tRNA precursor and analyzed the substrate shape recognition by bacterial ribonuclease P ribozyme and holoenzyme. The results showed the evidence for the presence of subsites for the recognition of the trna shape. We will discuss a new model for substrate recognition and the role of the protein component.
