Structural highlights
Function
ZINT_ECOLI May function as a periplasmic zinc chaperone or mediate direct transport of zinc from the periplasm to the cytoplasm under zinc-limited conditions. Binds zinc with high affinity, and can also bind cadmium, mercury or nickel. Preferentially binds Zn(2+) over Cd(2+). Contains one high affinity metal binding site, and can bind additional metal ions at other sites.[1] [2]
