Zinc-beta-lactamase L1 from stenotrophomonas maltophilia (mp2 inhibitor complex)Zinc-beta-lactamase L1 from stenotrophomonas maltophilia (mp2 inhibitor complex)
Structural highlights
FunctionBLA1_STEMA Has a high activity against imipenem. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedOne mechanism by which bacteria can escape the action of beta-lactam antibiotics is the production of metallo-beta-lactamases. Inhibition of these enzymes should restore the action of these widely used antibiotics. The tetrameric enzyme L1 from Stenotrophomonas maltophilia was used as a model system to determine a series of high-resolution crystal structures of apo, mono and bi-metal substituted proteins as well as protein-inhibitor complexes. Unexpectedly, although the apo structure revealed only few significant structural differences from the holo structure, some inhibitors were shown to induce amino acid side-chain rotations in the tightly packed active site. Moreover, one inhibitor employs a new binding mode in order to interact with the di-zinc center. This structural information could prove essential in the process of elucidation of the mode of interaction between a putative lead compound and metallo-beta-lactamases, one of the main steps in structure-based drug design. Structural insights into the design of inhibitors for the L1 metallo-beta-lactamase from Stenotrophomonas maltophilia.,Nauton L, Kahn R, Garau G, Hernandez JF, Dideberg O J Mol Biol. 2008 Jan 4;375(1):257-69.
