Is there a bridging ligand in metal-substituted zinc β-lactamases? A spectroscopic and theoretical answer

The spectral features of Co(II)-substituted metallo-β-lactamases were analyzed. Nuclear magnetic resonance (NMR) evidence is provided that shows no magnetic coupling between the two metal ions in Co(II),Co(II)-βLII (β-lactamase II from Bacillus cereus), suggesting that no bridging ligand connects th...
