Periplasmic oxidized-protein repair during copper stress in E. coli: a focus on the metallochaperone CusF.

A. Vergnes, C. Henry, G. Grassini, L. Loiseau, S. El Hajj, Y. Denis, A. Galinier, D. Vertommen, L. Aussel, B. Ezraty

This study shows that copper stress in E. coli activates the CusSR system to induce MsrPQ, which repairs oxidized methionine residues in CusF, maintaining copper efflux pump function.
