sulfate/thiosulfate ABC transporter~This property describes an ATP-binding cassette (ABC) transporter complex for sulfate and some related anions. Gene symbols for these proteins reflect a role of sulfate import in cysteine biosynthesis. The complex consists of four proteins, an ATP-binding protein CysA, two homologous permeases CysT and CysW, and a binding protein. In the model bacterium Escherichia coli, two binding proteins designated Sbp and CysP are present, and appear to facilitate transport of both sulfate and thiosulfate ions [1]. Unlike the case for phosphate uptake, ABC transport appears to be the only mechanism for sulfate uptake. An older report finds the sulfate transporter in E. coli also the sole transporter for selenate and selenite [2], and a review on the molybdate ABC transporter notes that, in absense of such a transporter, the sulfate transporter can take up molybdate [3]. |
