Metallo-β-lactamases (MBL) are zinc containing enzymes that cause resistance to β-lactam antibiotics. Here the authors show that the anti-Helicobacter pylori drug colloidal bismuth subcitrate inhibits MBLs by displacing the zinc ions with Bi(III), which is of great interest for the development of antibiotics.
