[[http://www.uniprot.org/uniprot/RNPA_STAAU RNPA_STAAU]] 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.

== Publication Abstract from PubMed ==
Staphylococcus aureus ribonuclease-P-protein subunit (RnpA) is a promising antimicrobial target that is a key protein component for two essential cellular processes, RNA degradation and transfer-RNA (tRNA) maturation. The first crystal structure of RnpA from the pathogenic bacterial species, S. aureus, is reported at 2.0 A resolution. The structure presented maintains key similarities with previously reported RnpA structures from bacteria and archaea, including the highly conserved RNR-box region and aromatic residues in the precursor-tRNA 5'-leader-binding domain. This structure will be instrumental in the pursuit of structure-based designed inhibitors targeting RnpA-mediated RNA processing as a novel therapeutic approach for treating S. aureus infections.
