sortase B;
SrtB

Hydrolases;
Acting on peptide bonds (peptidases);
Cysteine endopeptidases

The enzyme catalyses a cell wall sorting reaction in which a surface protein with a sorting signal containing a NXTN motif is cleaved. The resulting threonine carboxyl end of the protein is covalently attached to a pentaglycine cross-bridge of peptidoglycan.

In peptidase family C60.
