title: RNase MRP/RNase P: a structure-function relation conserved in evolution?
abstract: RNase P and RNase MRP are related ribonucleoproteins. RNase MRP processes mitochondrial precursor- (primer) RNAs, whereas RNase P cleaves precursor-tRNAs to produce their mature 5'-ends. Both RNase P and RNase MRP are associated with the Th/To ribonucleoprotein suggesting possible interrelated pathways and/or functions. All known RNase P and RNase MRP RNAs contain conserved structural elements possibly involved in catalysis/substrate binding, but these elements do not predict all cellular functions of the RNPs.
