EC 3.4.22.71

Accepted name: sortase B

Reaction: The enzyme catalyzes 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.

Other name(s): SrtB

Comments: In peptidase family C60.
