CD spectra of Ac-YGAKAAAAKAAAAKA(S/T)-NH2 peptides with serine (left) or threonine (right) modifications [unmodified Ser/Thr (free hydroxyl), Ser/ThrOPO3H– (pH 4), and Ser/ThrOPO32– (pH 8)]: unmodified Ser/Thr (green squares), dianionic phosphoserine/phosphothreonine (pH 8) (red circles), and monoanionic phosphoserine/phosphothreonine (pH 4) (open magenta circles). CD experiments were conducted in water with 10 mM phosphate (pH 7 or as indicated) and 25 mM KF at 0.5 °C.
