Figure 2.
Equilibrium ultracentrifugation of trpzips 1–3. The data shown are for 60 μM peptide samples and a rotor speed of 40 krpm. Apparent molecular weights obtained from the slopes (assuming ideal behavior) are shown; calculated formula weights are 1,608 for trpzips 1 and 2 and 1,648 for trpzip3. Trpzip1 data are offset vertically (ln absorbance −0.085) for clarity.
