Summary
Upregulated by GSNO in defined medium (anaerobic). [More information is available at EcoGene: EG13246]. CopA is a member of the P-type ATPase cation transporter family and is involved in copper homeostasis as an ATP-dependent exporter of monovalent copper under primarily aerobic conditions .

GeneRIFs: Gene References Into Functions

What's a GeneRIF?
  1. CopA chaperone is expressed in E. coli from the same gene that encodes the transporter. Some ribosomes translating copA undergo programmed frameshifting, terminate translation in the -1 frame, and generate the 70 aa-long polypeptide CopA(Z), which helps cells survive toxic copper concentrations. The high efficiency of frameshifting is achieved by the combined stimulatory action of a "slippery" sequence, an mRNA pseudoknot

  2. The distal N-terminal metal-binding domain transfers copper to the membrane-integral ion-binding sites of CopA, while the proximal metal-binding domain has a regulatory role by suppressing the catalytic activity of CopA in absence of copper.

  3. Data indicate that RNAP sigma(70)-can bind to copper efflux regulator (CueR)-promoter PcopA complex.

  4. copper-transporting ATPases, CopA and ATP7A, in both bacteria and macrophage are unique determinants of bacteria survival and identify an unexpected role for copper at the host-pathogen interface
