catalytic Activity CATALYTIC ACTIVITY: Reaction=The enzyme catalyzes a cell wall sorting reaction in which a surface protein with a sorting signal containing a LPXTG motif is cleaved between the Thr and Gly residue. The resulting threonine carboxyl end of the protein is covalently attached to a pentaglycine cross-bridge of peptidoglycan.; EC=3.4.22.70; Evidence={ECO:0000305|PubMed:22296345};

EC Number 3.4.22.70
Enzyme Function FUNCTION: Transpeptidase that anchors surface proteins to the cell wall. Recognizes Leu-Ala-x-Thr-Gly and Leu-Pro-x-Thr-Gly, with a preference for the former. Unlike the S.aureus sortase it cleaves not only the Thr-Gly motif but also the Ala-X bond; an Ala-Glu bond is a better substrate than the Thr-Gly motif in vitro. Among its possible substrates are the chaplins ChpA, ChpB and ChpC; this enzyme is more important for ChpC attachment than is SrtE1. A double knockout mutant of srtE1 and srtE2 shows a developmental defect in aerial hyphae formation more dramatic than that due to chaplin deletion. {ECO:0000269|PubMed:22296345}.
