Ribonuclease P protein component 4

Gene

rnp4

Organism
Pyrococcus furiosus (strain ATCC 43587 / DSM 3638 / JCM 8422 / Vc1)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

Functioni

Part of ribonuclease P, a protein complex that generates mature tRNA molecules by cleaving their 5'-ends. The RNA is catalytic, but its KM for pre-tRNA is 170-fold decreased in the presence of the 4 known protein subunits (Rnp1-4). The protein subunits also decrease the amount of Mg2+ needed for activity.UniRule annotation3 Publications

Catalytic activityi

Endonucleolytic cleavage of RNA, removing 5'-extranucleotides from tRNA precursor.UniRule annotation1 Publication

Cofactori

Zn2+UniRule annotation2 PublicationsNote: Binds 1 zinc ion per subunit.UniRule annotation2 Publications

Kineticsi

kcat is 9.5 min(-1). For enzyme reconstituted with RNA and 4 known subunits (Rnp1-4).

    Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
    100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
    90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
    50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
