Induction of L1 and L2 beta-lactamase production in Stenotrophomonas maltophilia is dependent on an AmpR-type regulator.

Antimicrobial agents and chemotherapy - 1 Apr 2008

Okazaki Aki, Avison Matthew B

Abstract excerpt

A divergently oriented ampR has been located upstream of blaL2 in Stenotrophomonas maltophilia. AmpR is necessary for L1 and L2 beta-lactamase induction in response to beta-lactam challenge, and activation of AmpR is sufficient to induce L1 and L2 production. L1 induction requires more activation of AmpR than does L2 induction.
