Active Transport of Organic Anions across the Human Erythrocyte Membrane
Erythrocytes, which constitute more than 40% of the blood volume and about 3% of the body mass, are an important, although frequently neglected, detoxification organ. The main route of xenobiotic metabolism in erythrocytes goes through the glutathione conjugation process, and subsequently comprises removal of the conjugates via the membrane active transport systems. In human erythrocyte membran...
متن کاملFacilitated transport of amino acids across organic phases and the human erythrocyte membrane.
1. An artificial facilitated amino-acid-transfer process operating across a chloroform phase is reported. 2. This process utilizes a family of bis(salicylamidato)copper(II) complexes. 3. A mechanism is proposed for this process and for its sensitivity towards cyanide and bathophenanthroline sulphonate. 4. Facilitated transfer of L-leucine in human erythrocytes has been shown to be inhibited by ...
متن کاملHydroxyl Ion Movements across the Human Erythrocyte Membrane
A stopped flow rapid reaction apparatus capable of following changes of +/-0.02 pH unit in 0.1 ml of solution in less than 0.005 sec has been developed, utilizing a commercially available pH-sensitive glass electrode. Using this instrument, extracellular pH at 37 degrees C was followed from less than 0.025 sec to 300 sec after mixing equal volumes of the following CO(2)-free solutions: (A) norm...
متن کاملTwo-dimensional structure of the membrane domain of human band 3, the anion transport protein of the erythrocyte membrane.
The membrane domain of human erythrocyte Band 3 protein (M(r) 52,000) was reconstituted with lipids into two-dimensional crystals in the form of sheets or tubes. Crystalline sheets were monolayers with six-fold symmetry (layer group p6, a = b = 170 A, gamma = 60 degrees), whereas the symmetry of the tubular crystals was p2 (a = 104 A, b = 63 A, gamma = 104 degrees). Electron image analysis of n...
متن کاملTransport of phosphoenolpyruvate through the erythrocyte membrane.
Phosphoenolpyruvate was transported through the erythrocyte membrane at low pH (4.5-6.5). The influx was observed not only in an iso-osmotic sucrose medium, but also in 0.1 M-citrate solution, but it was negligible in an iso-osmotic NaC1 solution. Efflux, however, was observed in both the sucrose and NaC1 solutions. Compounds derived from phosphoenolpyruvate by replacing the methene group by si...
