The Chromosome Determined Zinc Responsible (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. The role of Czr A in the Czr operon is described in further detail as part of the explanation of biological function. In addition to being a component of an operon, Czr A is also considered to be a metal sensor protein. While the immediate function of Czr A is gene regulation, this serves the larger purpose of acting to maintain an appropriate concentration of Zn <sup>2+</sup> | The Chromosome Determined Zinc Responsible (Czr) operon acts as described above, with Czr A acting as a regulator protein to the downstream gene Czr B.
