Abstract
⺠The E312/E343 double-Glu motif of tripeptidylpeptidase II is highly asymmetrical. ⺠E312 both blocks the active-site cleft at position P4 and acts as the prime docking residue. ⺠A salt bridge involving E312 conveys high exopeptidase selectivity. ⺠Substrate binding to the prime-site subsites enables weak endopeptidolysis.
