POP1 is a component of Ribonuclease P that cleaves the 5' leader from precursor tRNAs. The C-terminal domain of POP1 interacts with H1 RNA and has a stabilizing role. This domain adopts a beta-barrel structure that is structurally very similar to the C-terminal beta-barrel domains of eIF2 gamma, EF-Tu and tRNA thiouridylase MnmA [1].

These RNA-containing enzymes generate mature tRNA molecules by cleaving their 5' ends. This is a short N-terminal domain consisting of a small helical core and a long alpha-helix [2], which is enriched with positively charged residues involved in pre-tRNA substrate recognition [2].

The structure ...This family consists of several archaeal and eukaryotic proteins. The archaeal proteins are found to be expressed within ribosomal operons and several of the sequences are described as ribonuclease P protein subunit p29 proteins [1,2]. The structure of the RNase P subunit, Rpp29, from Methanobacterium thermoautotrophicum has been determined. Mth Rpp29 is a member of the oligonucleotide/oligosaccharide binding fold family. It contains a structured beta-barrel core and unstructured N- and C-terminal extensions bearing several highly conserved amino acid residues that could be involved in RNA contacts in the protein-RNA complex [2]. Rpp29 catalyses the endonucleolytic cleavage of RNA, removing 5'-extranucleotides from tRNA precursor. It interacts with the Rpp25 and Pop5 subunits.
