Structural analysis of the NaD1 CTPP. (A) CD spectrum of the 33 amino acid CTPP of NaD1 in 50 mM phosphate buffer pH 7.0 (dashes), 10% TFE (dots), 20% TFE (grey) and 30% TFE (black). (B) Secondary shift analysis of the CTPP in aqueous solution (black bars) and in 20% TFE (white bars). The secondary shifts were calculated by subtracting random coil Hα shifts [12] from the Hα shifts.
