Divalent cations have differential effects on the secondary structure of MtαIPMS and TIM barrel domain. A. Effect of increasing concentration of KCl (circle) and MgCl2 (square) on the CD ellipticity at 222 nm of MtαIPMS (open symbols) and TIM barrel domain (closed symbol). B. Effect of increasing concentration of ZnCl2 (up triangle) and CdCl2 (down triangle) on the CD ellipticity at 222 nm of MtαIPMS (open symbols) and TIM barrel domain (closed symbols).
