Think zinc: We have developed a new preparation method for generating the apo-enzyme of IMP-1 metallo-β-lactamase (apo-IMP-1) with the combination of a chelating agent (EDTA) and desalting column chromatography. An advantage of this method is that enzymatic activity of the apo-enzyme comparable to that observed with the native enzyme could be restored upon addition of ZnII ions (see scheme).
