INHERITANCE OF DIAPHORASE AND GLUCOSE-6-PHOSPHATE ISOMERASE IN EUSTOMA GRANDIFLORUM

Catalytic reactions of phosphoglucose isomerase with cyclic forms of glucose 6-phosphate and fructose 6-phosphate.

Yeast phosphoglucose isomerase is shown to use and produce both the u and the fi anomeric forms of fructofuranose 6-phosphate. Rapid quench techniques show a Z&fold preference in the utilization of the a! anomer over the /3 anomeric form. The previous report that the (Y anomer of glucopyranose-6-P is the preferred substrate form is confirmed. However the /3 anomer is also shown to react at a sl...

Characterization of Human Glucose - 6 - Phosphate Isomerase of Different Sizes

The accumulation of glucose 6-phosphate from glucose and its effect in an Escherichia coli mutant lacking phosphoglucose isomerase and glucose 6-phosphate dehydrogenase.

When presented with glucose, an Escherichia coli mutant lacking both phosphoglucose isomerase and glucose 6-phosphate dehydrogenase accumulated, internally, high concentrations (approximately 50 mM) of glucose 6-phosphate. It also accumulated glucose in polysaccharide form. Other metabolism of glucose, if any, was very restricted. The accumulation of glucose 6-phosphate was associated with inhi...

Glucose-6-Phosphate Dehydrogenase Deficiency and Neonatal Hyperbilirubinemia

Background: Jaundice is affecting over 60-80 percent of neonates in the first week of life. Glucose-6-phosphate dehydrogenase (G6PD) deficiency, which is an important cause of pathologic hyperbilirubinemia, can lead to hemolytic anemia, jaundice and kernicterus. The present study was performed to determine the prevalence of G6PD deficiency among icteric neonates in Shirvan, Iran. Methods: This...

Cloning and characterization of an anaerobically induced cDNA encoding glucose-6-phosphate isomerase from maize.

Anaerobic stress in maize (Zea mays L.) leads to a drastic alteration in gene expression and results in the selective synthesis of a small number of polypeptides named anaerobic proteins (Sachs et al., 1980). Other plants studied showed similar responses when subjected to an anaerobic environment (Russell et al., 1990). To date, the majority of the anaerobic proteins that have been identified w...
