Grouped By:  Matching UniProtKB accession

UniProtKB description:  Acts as a zinc chaperone in the AztABCD zinc transport system (By similarity). Directly transfers one zinc cation to the solute binding protein AztC; the transfer occurs without the formation of a stable interaction (By similarity). Binds 3 Zn(2+), two with high affinity and one with low affinity, and transfers only Zn(2+) bound to site 2 to AztC (PubMed:31428696).
