This entry represents the C-terminal domain of Ribonucleases P/MRP protein subunit POP1. 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.
Ribonucleases P/MRP protein subunit POP1, N-terminal
This entry represents a conserved region approximately 150 residues long located towards the N-terminus of the POP1 subunit that is common to both the RNase MRP and RNase P ribonucleoproteins (EC:3.1.26.5) [1]. These RNA-containing enzymes generate m ...
This entry represents a conserved region approximately 150 residues long located towards the N-terminus of the POP1 subunit that is common to both the RNase MRP and RNase P ribonucleoproteins (EC:3.1.26.5) [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].
