Permeability of rat liver microsomal membrane to glucose 6-phosphate.
Light-scattering measurements of osmotically induced changes in the size of rat liver microsomal vesicles pre-equilibrated in a low-osmolality buffer revealed the following. (1) The increase in extravesicular osmolality by addition of glucose 6-phosphate or mannose 6-phosphate (25 mM each) caused a rapid shrinking of microsomal vesicles. After shrinkage, a rapid swelling phase (t1/2 approx. 22 ...
متن کاملAccessibility of glucose 6-phosphate: phosphohydrolase to antibody attack in modified microsomal vesicles.
Recent investigations supported the existence of 2 components of the endoplasmic reticulum participating in the process of glucose 6-phosphate hydrolysis: the glucose 6-phosphate-specific transporter that mediates the movement of the substrate from the cytoplasmic membrane surface into the lumen and the unspecific phosphohydrolase on the luminal side of the membrane [ 1,2]. However, this model ...
متن کاملGlucose-6-Phosphate Dehydrogenase
Description Glucose-6-Phosphate Dehydrogenase (G6PD) deficiency is the most common human enzyme deficiency that mainly affects the red blood cells (RBCs). A defect in G6PD enzyme leads to the destruction of premature RBCs causing hemolytic anemia because the body can not compensate the destroyed RBCs. Thus, the affected individuals show jaundice (paleness, yellowing of the skin and whites of th...

متن کاملGlucose-6-phosphate dehydrogenase deficiency.
Glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common human enzyme defect, being present in more than 400 million people worldwide. The global distribution of this disorder is remarkably similar to that of malaria, lending support to the so-called malaria protection hypothesis. G6PD deficiency is an X-linked, hereditary genetic defect due to mutations in the G6PD gene, which ca...
