Protein attributes

Sequence length	119 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	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 By similarity. HAMAP-Rule MF_00227
Catalytic activity	Endonucleolytic cleavage of RNA, removing 5'-extranucleotides from tRNA precursor. HAMAP-Rule MF_00227
Subunit structure	Consists of a catalytic RNA component (M1 or RnpB) and a protein subunit By similarity.
Sequence similarities	Belongs to the RnpA family.
