Enzyme Information

3.4.22.70
Sortase A.
based on mapping to UniProt Q9S446
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.
-!- Belongs to peptidase family C60.
