Abstract

The genes for the protein (C5 protein) and RNA (M1 RNA) subunits of Escherichia coli RNase P have been subcloned and their products prepared in milligram quantities by rapid procedures. The interactions between the two subunits of the enzyme have been studied in vitro by a filter-binding technique. The stoichiometry of the subunits in the holoenzyme is 1:1. The dissociation constant for the specific interactions of the subunits in the holoenzyme complex is ~4 × 10^-10 m. C5 protein also interacts with various RNA molecules in a non-specific manner with a dissociation constant of 2 × 10^-8 to 6 × 10^-8 m. Regions of M1 RNA required for interaction with C5 protein have been defined by deletion analysis and footprinting techniques. These interactions are localized primarily between nucleotides 82 to 96 and 170 to 270 of M1 RNA.
