Functional characterization of OXA-57, a class D beta-lactamase from Burkholderia pseudomallei

Antimicrob Agents Chemother. 2005 Apr;49(4):1639-41. doi: 10.1128/AAC.49.4.1639-1641.2005.

Abstract

Class D beta-lactamase OXA-57 was identified in a range of isolates of Burkholderia pseudomallei and Burkholderia thailandensis. Comparative kinetic analyses of wild-type and mutant forms of B. pseudomallei OXA-57 are reported. Implications of these data for beta-lactam resistance and the proposed role of Ser-104 in beta-lactam hydrolysis are discussed.
