A high affinity site for sugar transport at the inner face of the human erythrocyte membrane?
A disagreement centering on a method of analysis as to the existence of a high affinity site for glucose transport at the inner face of the human red cell membrane is resolved by using direct fitting methods to confirm the original parameter estimates.
متن کاملEvidence for two asymmetric conformational states in the human erythrocyte sugar-transport system.
6-O-methyl-, 6-O-propyl-, 6-O-pentyl- and 6-O-benzyl-D-galactose, and 6-O-methyl-, 6-O-propyl- and 6-O-pentyl-D-glucose inhibit the glucose-transport system of the human erythrocyte when added to the external medium. Penetration of 6-O-methyl-D-galactose is inhibited by D-glucose, suggesting that it is transported by the glucose-transport system, but the longer-chain 6-O-alkyl-D-galactoses pene...
متن کاملGlucose Transport Carrier in Human Erythrocyte Membranes
The effect of D-glucose on dinitrophenylation of membrane proteins of human erythrocyte ghosts by I-fluoro-2,4-dinltrobenzene was studied in the absence and in the presence of D-glucose. A double isotopic, differential labeling technique followed by gel electrophoresis of extracts in the presence of sodium dodecyl sulfate revealed the presence of a polypeptide, or polypeptides, in human erythro...
متن کاملErythrocyte nucleoside and sugar transport. Endo-beta-galactosidase and endoglycosidase-F digestion of partially purified human and pig transporter proteins.
Nucleoside- and glucose-transport proteins isolated from human erythrocyte membranes were photoaffinity-labelled with [3H]nitrobenzylthioinosine and [3H]cytochalasin B, respectively, and subjected to endo-beta-galactosidase or endoglycosidase-F digestion. Without enzyme treatment the two radiolabelled transporters migrated on SDS/polyacrylamide gels with the same apparent Mr (average) of 55,000...
متن کاملActive 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...
