Fig. 2: Overall levels of hABCB6^core in complex with Cd(II) and GSH (or PC2).

a Cryo-EM map of Cd(II):GSH-bound hABCB6^core. The two monomers are colored blue and orange, respectively. The nanodisc is depicted in a gray surface representation. b Molecular structure of Cd(II):GSH-bound hABCB6^core. Cd(II) ion and GSH are shown in green and cyan sphere representation, respectively. The area enlarged in Fig. 4a is boxed. Single primes are used for the residues (or helices) of one monomer to differentiate them from those of the other monomer. c Cryo-EM map of Cd(II):PC2-bound hABCB6^core. The two monomers are colored light blue and light orange, respectively. d Molecular structure of Cd(II):PC2-bound hABCB6^core. The area enlarged in Fig. 4c is boxed.
