Functioni

RNaseP catalyzes the removal of the 5'-leader sequence from pre-tRNA to produce the mature 5'-terminus. It can also cleave other RNA substrates such as 4.5S RNA. The protein component plays an auxiliary but essential role in vivo by binding to the 5'-leader sequence and broadening the substrate specificity of the ribozyme.UniRule annotation

Catalytic activityi

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