چکیده انگلیسی
Many bacteria use an ABC transporter for high-affinity uptake of zinc with a cluster 9 solute-binding protein. Other members of this protein family transport manganese. At present, it is not always possible to distinguish zinc-specific and manganese-specific transporters on the basis of sequence analysis. Low-affinity ZIP-type zinc transporters in bacteria have also been identified. Most high-affinity zinc uptake systems are regulated by Zur proteins, which form at least three unrelated subgroups of the Fur protein family (regulators of iron transport). High-affinity transport of zinc out of the periplasmic space poses a problem to the cell because zinc is a cofactor of several periplasmic enzymes. Certain zinc-binding proteins in the periplasm might function as chaperones to supply these enzymes with zinc.
