===Czr Operon=== | ===Czr Operon=== | ||
The | The <u>C</u>hromosome determined <u>z</u>inc <u>r</u>esponsible (Czr) operon acts as described above, with Czr A acting as a regulator protein to the downstream gene Czr B. The Czr B gene codes for a Zn<sup>+2</sup> pump, so Czr A is responsible for controlling the transport of Zn<sup>+2</sup> out of the cell. Because of its role in regulating Zn<sup>+2</sup> levels, Czr A is considered a metal sensor protein. This allows Czr A to regulate the Czr operon to maintain an appropriate concentration of Zn<sup>+2</sup> inside the cell membrane. | ||
