Abstract

In a search for genes responsible for the accumulation of antimonite in Escherichia coli, TnphoA was used to create a pool of random insertional mutants, from which one antimonite-resistant mutant was isolated. Sequence analysis showed that the TnphoA insertion was located in the glpF gene, coding for the glycerol facilitator GlpF. The mutant was shown to be defective in polyol transport by GlpF. These results suggest that in solution Sb(III) is recognized as a polyol by the glycerol facilitator.
