ZupT determines changes in intracellular zinc concentration of Lack Previous studies have shown that zinT are coregulated by Zur and that ZinT accumulation is strongly induced by EDTA and repressed by zinc .23 The addition of 0.5 μM ZnSO4 to the culture medium causes the complete abrogation of ZinT accumulation in a wild type Salmonella strai
As zinT expression is under the direct control of Zur , the main transcriptional regulator strongly support the hypothesis that the absence of zupT further reduces the ability of Salmonella enterica to import zinc from the environment .
