A 105-kDa protein is required for yeast mitochondrial RNase P activity.

RNase P from the mitochondria of Saccharomyces cerevisiae was purified to near homogeneity > 1800-fold with a yield of 1.6% from mitochondrial extracts. The most abundant protein in the purified fractions is, at 105 kDa, considerably larger than the 14-kDa bacterial RNase P protein subunits. Oligonucleotides designed from the amino-terminal sequence of the 105-kDa protein were used to identify and isolate the 105-kDa protein-encoding gene. Strains carrying a disruption of the gene for the 105-kDa protein are viable but respiratory deficient and accumulate mitochondrial tRNA precursors with 5' extensions. As this is the second gene known to be necessary for yeast mitochondrial RNase P activity, we have named it RPM2 (for RNase P mitochondrial).[1]
