GO:0005655:   nucleolar ribonuclease P complex
A ribonuclease P complex located in the nucleolus of a eukaryotic cell, where it catalyzes the 5" endonucleolytic cleavage of precursor tRNAs to yield mature tRNAs. Eukaryotic nucleolar ribonuclease P complexes generally contain a single RNA molecule that is necessary but not sufficient for catalysis, and several protein molecules.
