Ribonuclease P protein component 4

UniProtKB accession:  Q8U0H6

Grouped By:  Matching UniProtKB accession

UniProtKB description:  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 Mg(2+) needed for activity.
