[https://www.uniprot.org/uniprot/SRTB_STAA8 SRTB_STAA8] Transpeptidase that anchors surface proteins to the cell wall (PubMed:11830639, PubMed:15718231, PubMed:24519933) (Probable). Recognizes and modifies its substrate by proteolytic cleavage of a C-terminal sorting signal. Following cleavage, a covalent intermediate is formed via a thioester bond between the sortase and its substrate, which is then transferred and covalently attached to the cell wall (Probable) (PubMed:24519933). This sortase recognizes an Asn-Pro-Gln-Thr-Asn (NPQTN) motif in IsdC, which is cleaved by the sortase between the threonine and aspargine residues; may only have 1 substrate in this bacterium (Probable). May be dedicated to the process of iron acquisition during bacterial infection (Probable).<ref>PMID:11830639</ref> <ref>PMID:15718231</ref> <ref>PMID:24519933</ref> <ref>PMID:11830639</ref> <ref>PMID:15718231</ref> <ref>PMID:29690584</ref>
