a) Ribbon diagram for the 20 structures of (S)-HMG-ACPI. b) Mean structure of HMG-ACPI. The amino acids which undergo chemical shift perturbations once the 4′-Ppant arm is added are labeled in blue (CSP >0.04ppm), amino acids which undergo slight chemical shift perturbations when HMG is added to the 4′-Ppant arm are indicated in magenta (CSP >0.04ppm). The shifts are located around the attachment site of the substrate on helix II and helix III.
