Copper homeostasis protein CutC was originally thought to be involved in copper tolerance in Escherichia coli, as mutation in the corresponding gene lead to an increased copper sensitivity [1]. However, this phenotype has been later reported to depend on the levels of he mRNA-interfering complementary RNA regulator MicL, which is transcribed from a promoter located within the coding sequence of the cutC gene in enterobacteria [2]. In the plant pathogen Xylella fastidiosa, this protein has been reported as specific for copper efflux [3]. The structure of this protein in the bacteria Shigella flexneri showed a monomer structure that adopts a common TIM beta/alpha barrel with eight beta strands surrounded by eight alpha-helices [4]. The human homologue of this protein, whose structure showed a potential copper-binding site, has an important role in intracellular copper homeostasis [5,6].	Domain
