The varieties of ribonuclease P
Abstract
Ribonuclease P is a ribozyme involved in tRNA processing that is present in all cells and organelles that synthesize tRNA. Most of our understanding of ribonuclease P derives from studies of the bacterial enzyme. This enzyme has been characterized biochemically and a secondary structure for the RNA subunit has been proposed. Isolation and characterization of ribonuclease P from diverse Archaea and Eukarya are now modifying and adding to our model of this unusual enzyme. The latter instances of RNase P differ from the bacterial version, but similarities are emerging.
