Tendency of 4.1R-CTD64 to adopt an α-helix conformation. A: Conformational Δδ¹³C_α (Δδ¹³C_α = δ¹³C_{α, experimental}- δ¹³C_{α, random coil}, ppm) chemical shifts as a function of sequence. Positive values indicate α-helix structure. B: Conformational Δδ¹³C_β (Δδ¹³C_β = δ¹³C_{β, experimental}- δ¹³C_{β, random coil}, ppm) chemical shifts as a function of sequence. Negative values indicate α-helix structure. C: Theoretical prediction of helical percentage at 5°C and pH 5.0 by AGADIR [23] as a function of residue number.
