Disruption of protein–protein interactions: design of a synthetic receptor that blocks the binding of cytochrome c to cytochrome c peroxidase
Abstract
Synthetic receptor 1 has been found via fluorescence titration to compete effectively with cytochrome c peroxidase for binding cytochrome c (Cc), forming 1∶1 Cc∶1 complex with a binding constant of (3 ± 1) × 108 M−1, and to disrupt Cc∶Apaf-1 complex, a key adduct in apoptosis.
