Single transporter for sulfate, selenate, and selenite in Escherichia coli K-12.
Lindblow-Kull C., Kull F.J., Shrift A.
A Michaelis-Menten kinetic analysis of the transport of sulfate, selenate, and selenite into Escherichia coli K-12 showed that the three dianions were transported by the same carrier. Km values, used as a measure of the affinity of each ligand for the carrier, showed that sulfate was bound 5 times ... >> More
A Michaelis-Menten kinetic analysis of the transport of sulfate, selenate, and selenite into Escherichia coli K-12 showed that the three dianions were transported by the same carrier. Km values, used as a measure of the affinity of each ligand for the carrier, showed that sulfate was bound 5 times more tightly than selenate and 37 times more tightly than selenite. The specificity ratio, Vmax/Km, also indicated that sulfate was the preferred ligand. There was little difference in the ratios for selenate and selenite. << Less

Bacterial transport of sulfate, molybdate, and related oxyanions.

Sulfur is an essential element for microorganisms and it can be obtained from varied compounds, sulfate being the preferred source. The first step for sulfate assimilation, sulfate uptake, has been studied in several bacterial species. This article reviews the properties of different bacterial (and archaeal) transporters for sulfate, molybdate, and related oxyanions. Sulfate uptake is carried out by sulfate permeases that belong to the SulT (CysPTWA), SulP, CysP/(PiT), and CysZ families. The oxyanions molybdate, tungstate, selenate and chromate are structurally related to sulfate. Molybdate is transported mainly by the high-affinity ModABC system and tungstate by the TupABC and WtpABC systems. CysPTWA, ModABC, TupABC, and WtpABC are homologous ATP-binding cassette (ABC)-type transporters with similar organization and properties. Uptake of selenate and chromate oxyanions occurs mainly through sulfate permeases. << Less
