Protein Domain : Sortase family IPR005754

Type	Family
Description	This family includes Staphylococcus aureus sortase, a transpeptidase that attaches surface proteins by the Thr of an LPXTG motif to the cell wall. It also includes a protein required for correct assembly of an LPXTG-containing fimbrial protein, a set of homologous proteins from Streptococcus pneumoniae, in which LPXTG proteins are common. However, related proteins are found in Bacillus subtilis and Methanobacterium thermoautotrophicum, in which LPXTG-mediated cell wall attachment is not known [ ]. Sortase refers to a group of prokaryotic enzymes which catalyze the assembly of pilins into pili, and the anchoring of pili to the cell wall [ ]. They act as both proteases and transpeptidases []. Sortase, a transpeptidase present in almost all Gram-positive bacteria, anchors a range of important surface proteins to the cell wall [, ]. The sortases are thought to be good targets for new antibiotics as they are important proteins for pathogenic bacteria [ ].
