(A) Far-UV CD spectra of PDZ2 incubated at a concentration of 0.4 mg mL⁻¹, in 20 mM sodium phosphate, 1 M NaCl, pH 7.0, 37°C with (solid line) and without (dotted line) agitation at 750 rpm for 24 h. (B) Change of the mean residue ellipticity at 222 nm as a function of incubation time under agitation in the conditions described for panel A.
