OXA-253, a variant of the carbapenem-hydrolyzing class D β-lactamase OXA-143 in Acinetobacter baumannii.
The carbapenem-hydrolyzing class D β-lactamase OXA-253 was identified in an Acinetobacter baumannii clinical isolate belonging to sequence type 113 (ST113) in Brazil. OXA-253 shares 93.8% amino acid identity with OXA-143. The blaOXA-253 gene is located on a ca. 20-kb plasmid. The genetic environment of the blaOXA-253 gene shares the highest identity with ubiquitous GR2 group plasmids usually ca...
متن کاملCrystal structure of the class D beta-lactamase OXA-10.
We report the crystal structure of a class D beta-lactamase, the broad spectrum enzyme OXA-10 from Pseudomonas aeruginosa at 2.0 A resolution. There are significant differences between the overall fold observed in this structure and those of the evolutionarily related class A and class C beta-lactamases. Furthermore, the structure suggests the unique, cation mediated formation of a homodimer. K...
