Many surface proteins of Gram-positive bacteria, which play important roles during the pathogenesis of human infections, are anchored to the cell wall envelope by a mechanism requiring sortases. Sortase B, a cysteine transpeptidase from Staphylococcus aureus, cleaves the C-terminal sorting signal of IsdC at the NPQTN motif and tethers the polypeptide to the pentaglycine cell wall cross-bridge ...
