TABLE 5.
Changes in the mRNA levels from a number of genes in response to Zn2+ deficiency
The gene names are the primary names on Ecogene. The gene descriptions are from Ecogene.
| Gene | b number | Gene product | Fold change | p value |
|---|---|---|---|---|
| yodB | b1974 | Function unknown | 2.38 | 0.0725 |
| zur | b4046 | Repressor for znuABC, the zinc high affinity transport genes; dimer; binds two Zn(II) ions per monomer | 1.37 | 0.9578 |
| znuC | b1858 | High affinity ABC transport system for zinc | 1.36 | 0.2294 |
| znuB | b1859 | High affinity ABC transport system for zinc | 1.34 | a |
| zntR | b3292 | Zinc-responsive activator of zntA transcription | 1.34 | 0.4857 |
| zraS | b4003 | Two component sensor kinase for ZraP; responsive to Zn2+ and Pb2+; autoregulated; regulation of Hyd-3 activity is probably due to cross-talk of overexpressed protein | 1.32 | 0.1109 |
| zraP | b4002 | Zinc-binding periplasmic protein; responsive to Zn2+ and Pb2+; regulated by zraSR two-component system; rpoN-dependent | 1.25 | 0.9322 |
| yiiP | b3915 | Iron and zinc efflux membrane transporter; cation diffusion facilitator family; dimeric | 1.17 | 0.2742 |
| zitB | b0752 | Zn(II) efflux transporter; zinc-inducible | 1.09 | 0.9571 |
| zntA | b3469 | Zn(II), Cd(II), and Pb(II) translocating P-type ATPase; mutant is hypersensitive to Zn2+ and Cd2+ salts | 1.07 | 0.9285 |
| spy | b1743 | Periplasmic protein induced by zinc and envelope stress, part of cpxR and baeSR regulons | 1.03 | 0.8314 |
| zraR | b4004 | Two component response regulator for zraP; responsive to Zn2+ and Pb2+; autoregulated; regulation of Hyd-3 activity is probably due to cross-talk of overexpressed protein | 0.95 | 0.9315 |
| zupT | b3040 | Zinc and other divalent cation uptake transporter | 0.88 | 0.3258 |
