Escherichia coli K-12 substr. MG1655 Protein: copper binding protein CutA



Gene: cutA Accession Numbers: EG12177 (EcoCyc), b4137, ECK4131

Synonyms: cutA1

Regulation Summary Diagram: ?

Subunit composition of copper binding protein CutA = [CutA]3
         copper binding protein CutA = CutA

Summary:
CutA is a copper-binding protein that is also required for copper tolerance.

Mutants lacking CutA function show increased copper sensitivity and uptake. CutA is also involved in tolerance of zinc, nickel, cobalt and cadium. It is induced by the presence of copper, zinc, nickel and cobalt, and to a lesser extent cadmium, manganese and silver [Fong95].

The crystal structure of CutA has been determined to 1.7 Å resolution. It forms a trimer [Arnesano03].

CutA can bind copper in vitro [Arnesano03].
