There are no reports concerning glutathione-S-conjugates transport in prokaryotic cells, although many studies have been performed in eukaryotic systems. This study demonstrates that glutathione S-conjugates (2,4-dinitrophenyl-S-glutathione and bimane-S-glutathione) are transported also out of Escherichia coli K12 cells. This transport is inhibited by(More)
Molecular masses of functional units of two components of 2, 4-dinitrophenyl-S-glutathione (DNP-SG) transport across the erythrocyte membrane determined by radiation inactivation were 437 +/- 69 kDa for the high-affinity component and 466 +/- 67 kDa for the low-affinity component. These results confirm that the multidrug resistance-associated protein (MRP)(More)
Pig erythrocyte membrane Mg2+-ATPase activity was stimulated by various glutathione S-conjugates. For alkyl S-conjugates, the Km for the stimulation was lower, the more hydrophobic was the conjugate. 2,4-Dinitrophenyl-S-(N-acetyl)cysteine also stimulated the Mg2+-ATPase activity, suggesting a low specificity of the ¿glutathione S-conjugate pump¿. The Km(More)
