The Chromosome Determined Zinc Responsible (Czr) operon acts as described above, with Czr A acting as the regulator protein. As such, Czr A is responsible for controlling the transcription of the rest of the operon and by extension, 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> in the cell. | The Chromosome Determined Zinc Responsible (Czr) operon acts as described above, with Czr A acting as the regulator protein.
