Cuprous oxidase activity of CueO from Escherichia coli

J Bacteriol. 2004 Nov;186(22):7815-7. doi: 10.1128/JB.186.22.7815-7817.2004.

Abstract

We have found CueO from Escherichia coli to have a robust cuprous oxidase activity, severalfold higher than any homologue. These data suggest that a functional role for CueO in protecting against copper toxicity in vivo includes the removal of Cu(I).
