Sulfate permeasesphylogenetic diversity of sulfate transport.
Sulfate uptake, the first step of sulfate assimilation in all organisms, is a highly endoergic, ATP requiring process. It is under tight control at the transcriptional level and is additionally modulated by posttranslational modifications, which are not yet fully characterized. Sulfate anion is taken up into the cell by specific transporters, named sulfate permeases, located in the cell membran...
متن کاملSulfate transport in human neutrophils
The mechanism by which SO4(2-) is transported across the plasma membrane of isolated human neutrophils was investigated. Unlike the situation in erythrocytes, SO4(2-) and other divalent anions are not substrates for the principal Cl-/HCO3- exchange system in these cells. At an extracellular concentration of 2 mM, total one-way 35SO4(2-) influx and efflux in steady-state cells amounted to approx...
متن کاملRegulation of sulfate transport in Salmonella typhimurium.
Dreyfuss, Jacques (Princeton University, Princeton, N.J.), and Arthur B. Pardee. Regulation of sulfate transport in Salmonella typhimurium. J. Bacteriol. 91:2275-2280. 1966.-The transport of sulfate into Salmonella typhimurium is an active process. Intracellular and extracellular sulfate are in rapid equilibrium. Although the entry process requires energy, the exit of sulfate and the exchange o...
متن کاملRenal tubular transport of inorganic sulfate.
GLOBUS, DAVID L., E. LOVELL BECKER AND DAVID D. THOMPSON. Renal tubular tran.@ort of inorganic sulfate. Am. J. Rh ysiol. 200(5): 1105-1110. I g6 I .-The urinary excretion of radiosulfate by the dog was investigated after a rapid injection into one renal artery. Radiosulfate appeared in the urine before simultaneously injected creatinine. After the plasma sulfate concentration had been elevated,...
متن کاملIbuprofen-induced changes in sulfate renal transport.
Nonsteroidal anti-inflammatory drugs (NSAIDs) increase sulfate renal clearance and decrease the fractional reabsorption of sulfate by the kidneys. The mechanism of this alteration of inorganic sulfate homeostasis is unknown. The objectives of this study were 1) to investigate if sulfate renal transport is altered in isolated membrane vesicles after pretreatment of animals in vivo with ibuprofen...
