Figure 2From: Modeling Escherichia coli signal peptidase complex with bound substrate: determinants in the mature peptide influencing signal peptide cleavageA model of the DsbA 13–25 in complex with E. coli SPase. A model of the DsbA 13–25 precursor protein (Cα trace in black) bound to the active site of E. coli SPase (schematic cartoon diagram in grey) illustrating a pronounced twist in the peptide backbone between P3 and P1' at the catalytic site.Back to article page
