Function and Biology Details

Reaction catalysed:
The enzyme catalyzes a cell wall sorting reaction in which a surface protein with a sorting signal containing a NPXTN motif is cleaved between the Thr and Asn residue. The resulting threonine carboxyl end of the protein is covalently attached to a pentaglycine cross-bridge of peptidoglycan.
