== Publication Abstract from PubMed ==
The X-ray crystal structure of AmpC beta-lactamase (AmpC(D)) with a tripeptide deletion (Gly286-Ser287-Asp288) produced by Escherichia coli HKY28, a ceftazidime-resistant strain, was determined at a resolution of 1.7 A. The structure of AmpC(D) suggests that the tripeptide deletion at positions 286-288 located in the H10 helix causes a structural change of the Asn289-Asn294 region from the alpha-helix present in the native AmpC beta-lactamase of E. coli to a loop structure, which results in a widening of the substrate-binding site.
