The gene coding for the AU-rich RNA required for mitochondrial RNase P activity in Saccharomyces cerevisiae codes for a 490-base RNA while that in Candida glabrata codes for a 227-base RNA. We have detected a 140-nucleotide RNA coded by the mitochondrial DNA from Saccharomycopsis fibuligera by hybridization with an oligonucleotide complementary to a conserved sequence found in mitochondrial and prokaryotic RNase P RNAs. DNA sequence analysis of the mitochondrial DNA from the region coding for this RNA revealed a second conserved sequence block characteristic of RNase P RNA genes and the presence of a downstream tRNA(Pro) gene. Like previously characterized mitochondrial RNase P RNAs, this small RNA is extremely AU-rich. The discovery of this 140-base RNA suggests that naturally occurring RNase P RNAs may be quite small.
