Figure 2.

Ultra violet-vis absorption (a, c and e) and circular dichroism (CD (b, d and f) spectra of the following single species recombinantly synthesized in the corresponding metal-enriched media (Cd2+, Zn2+, and Cu2+): Cd6-HpCdMT (a, b), Zn6-HpCdMT (c, d) and Cu12-HpCuMT (e, f). Panel (b) also encloses (thin line) the CD spectra of the Cd6-HpCdMT species prepared in vitro by addition of 6 Cd2+ equivalents to Zn6-HpCdMT. MT, metallothionein.
