Imipenem, meropenem, and biapenem were generously supplied by Merck, Zeneca Pharmaceuticals, and Lederle (Japan), respectively.
also reported stopped-flow fluorescence studies when using cefaclor and meropenem as substrates, and K S values for these substrates were reported to be 710 ± 180 and 272 ± 112 μM, respectively [ 40 ] . However in our hands, the rates of substrate hydrolysis were so fast when using wild-type L1 that we could not use substrate concentrations high enough to saturate the enzyme.
The changes in molar absorptivities (Δε) used to quantitate products were (in M -1cm -1): nitrocefin, Δε 485 = 17,420; cephalothin, Δε 265 = -8,790; cefoxitin, Δε 265 = -7,000; cefaclor, Δε 280 = -6,410; imipenem, Δε 300 = -9,000; meropenem, Δε 293 = -7,600; biapenem, Δε 293 = -8,630; ampicillin, Δε 235 = -809; and penicillin G, Δε 235 = -936.
Instead, we predict that the insertion of an aspartic acid into the active site at position 224 results in a change in the hydrogen bonding network in L1; this hydrogen bonding network is extensive in all metallo-β-lactamases that have been characterized crystallographically [ 37 42 44 45 48 49 62 63 ] . The N233D mutant also exhibited greatly reduced k cat values for biapenem and meropenem but not for imipenem or any of the other substrates tested.
The k cat values exhibited by these mutants for all substrates also differed by less than a factor of 4, except when biapenem and meropenem were used as substrates for the N233D mutant.
