Structural highlights
Function
RNP2_PYRFU 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.[1] [2] [3]
