A Na+:H+ antiporter and a molybdate transporter are essential for arsenite oxidation in Agrobacterium tumefaciens.

Journal of bacteriology - 1 Feb 2006

Abstract excerpt

Transposon Tn5-B22 mutagenesis was used to identify genetic determinants required for arsenite [As(III)] oxidation in an Agrobacterium tumefaciens soil isolate, strain 5A. In one mutant, the transposon interrupted modB, which codes for the permease component of a high-affinity molybdate transporter. In a second mutant, the transposon insertion occurred in mrpB, which is part of a seven-gene operon encoding an...
