Figure 5. Averaged theoretical amide I response of collagen-like peptide molecules for “out of plane” rotation.

Normalized amide I response for four different collagen-like peptide structures (ID: 1BKV, 1CGD, 1QSU) that are rotated in the plane XZ [from (φ = 90°, θ = 90°) to (φ = 0°, θ = 90°)] vs the polarization angle of the incident light. The responses have been averaged at angles ω = 0°, ω = 90°, ω = 180°, ω = 270°. All the molecules exhibit a similar trend independent from which collagen-like peptide crystal structure. The average responses for all the selected structures are marked in bold.
