Abstract
The rnpA mutation, A49, in Escherichia coli reduces the level of RNase P at 43°C because of a temperature-sensitive mutation in C5 protein, the protein subunit of the enzyme. Microarray analysis reveals the expression of several noncoding intergenic regions that are increased at 43°C compared with 30°C. These regions are substrates for RNase P, and they are cleaved less efficiently than, for example, tRNA precursors. An analysis of the tna, secG, rbs , and his operons, all of which contain RNase P cleavage sites, indicates that RNase P affects gene expression for regions downstream of its cleavage sites.
