Reyes, Angélica; Leiva, Andrea; Cambiazo Ayala, Liliana; Méndez, Marco; González Canales, Mauricio (2006)Copper is an essential and toxic trace metal for bacteria and, therefore, must be tightly regulated in the cell. Enterococcus hirae is a broadly studied model for copper homeostasis. The intracellular copper levels in ...
