Crystal structures of type T archaeal ribonuclease P Rpp30, Rpp30/Pop5, and L7Ae provide insights into a reduced RNase P
Modeling of the RNA subunit suggests a structure closely related to the RNA components of other RNase P complexes, but with a minimal S-domain containing only a single T-loop, which supports the formation of an RNase P complex that retains all the elements needed for tRNA recognition and processing.
