Fig. 7 — CD spectra recorded during the titrations of Zn-βSpMTA (A, B) and Zn-βSpMTB (C, D) with Cd(II) at pH 7. The effect of the addition of S²⁻ to βSpMTB is also shown (F), as well as the CD superimposition of in vivo (red) and in vitro (black) Cd-βSpMTA (E) and Cd-βSpMTB (G) species obtained after addition of 3 Cd(II) equivalents to Zn-βSpMTA or after an acidification/reneutralization process of Cd-βSpMTB plus addition of 3 S²⁻ equivalents.
