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+): Cd 6 -HpCdMT (a, b), Zn 6 -HpCdMT (c, d) and Cu 12 -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.
