Saccharolobus solfataricus | Sulfolobus responds to exposure to a sublethal copper excess by the transient active transcription of the copA gene. The copA transcript reaches a peak 1 h after treatment, corresponding to approximately 35fold the uninduced level. Thereafter, the transcript level decreases until a steady-state level of 2-3fold induction is reached in the following 16 h. In cells cultured for several generations in the presence of 0.75 mM copper, the amount of copA transcript is maintained at 2-3fold the uninduced level, indicating that its rate of expression is maintained constant during longterm exposures, provided the concentration of copper do not change | up |

physiological function | the constitutive expression of copTA probably provides a constant and low level supply of the protein CopT and the Cu+-exporting ATPase CopA that maintain homeostasis, allowing the cell to adjust to small fluctuations in copper levels under normal condition | Saccharolobus solfataricus |
