Transport of different cations by ZntB. Transport of different cations (added at 1 min and colour-coded: black—20 µM Zn2+, red—20 µM Cd2+, blue—100 µM Ni2+, green—200 µM Co2+, dark blue—empty liposomes with 20 µM Zn2+, magenta—empty liposomes with 200 µM Co2+) assayed by the fluorophore Fluozine-1 trapped inside the proteoliposomes
