Abstract

Ribonuclease P (RNase P) is a ribonucleoprotein complex involved in the processing of the 5′ leader sequence of precursor tRNA (pre-tRNA). RNase P in the hyperthermophilic archaeon Pyrococcus horikoshii OT3 consists of RNA and five protein subunits (Ph1481p, Ph1496p, Ph1601p, Ph1771p, and Ph1877p). In vivo interactions among five protein subunits of RNase P in P. horikoshii OT3 were examined using a yeast two-hybrid system. The analysis indicates that proteins Ph1481p and Ph1601p interact strongly with Ph1877p and Ph1771p respectively, whereas Ph1481p interacts moderately with Ph1601p. In contrast, no interaction was detected between Ph1496p and the other four proteins. Co-immunoprecipitation analysis confirmed the interactions obtained by yeast two-hybrid assay.
