Naturally occurring Class A ss-lactamases from the Burkholderia cepacia complex.

Antimicrobial agents and chemotherapy - 1 Mar 2009

Abstract excerpt

Chromosomally encoded ss-lactamases from the Burkholderia cepacia complex species (formerly Pseudomonas cepacia) were characterized. Cloning and sequencing identified an Ambler class A ss-lactamase (PenB) from B. cenocepacia. It shares 82% amino acid identity with the PenA ss-lactamases previously identified from B. multivorans 249. Its expression was dependent upon a LysR-type regulatory protein. Its...
