Oct 22 2018018332Copper containing enzymes perform fundamental functions by activating dioxygen O2 and therefore allowing chemical energy transfer for aerobic metabolism The copper dependence of O2 transport metabolism and production of signalling molecules are supported by molecular systems that regulate and preserve tightly bound static and weakly bound dynamic cellular copper pools.
Copper is an important cofactor for many enzymes however high levels of copper are toxic Therefore bacteria must ensure there is sufficient copper for use as a cofactor but more importantly must limit free intracellular levels to prevent toxicity In this study we have used DNA microarray to identify Staphylococcus aureus copper responsive genes Transcriptional profiling of S aureus.
