Effect of ATP on glucose-6-phosphate isomerase from Bacillus caldotenax
BBA - Proteins and Proteomics, 1982Glucose-6-phosphate isomerase (D-glucose-6-phosphate ketol-isomerase, EC 5.3.1.9) from Bacillus caldotenax exhibits negative cooperativity in enzyme activity. Fructose 1-phosphate, fructose, 1,6-bisphosphate, phosphoenolpyruvate, 6-phosphogluconate, 3-phosphoglycerate, ATP and Pi competitively inhibit the enzyme and abolish negative cooperativity in ...

Purification and characterization of glucose-6-phosphate isomerase from Bacillus stearothermophilus
Archives of Biochemistry and Biophysics, 1971Abstract Glucose-6-phosphate isomerase (EC 5.3.1.9) has been purified from Bacillus stearothermophilus to a state in which it is homogeneous, both ultracentrifugally and electrophoretically. The sedimentation coefficient ( s 20, w ) and molecular weight of the enzyme are 7.4S and 172,000. The enzyme exhibits a maximum activity at 70 °.

Molecular basis of the isozymes of bovine glucose-6-phosphate isomerase
Archives of Biochemistry and Biophysics, 1986Glucose-6-phosphate isomerase occurs in different bovine tissues as multiple, catalytically active isozymes which can be resolved by polyacrylamide gel electrophoresis (PAGE) and isoelectric focusing (IEF). Most differentiated tissues have five distinct forms with apparent pI values of 7.2, 7.0, 6.8, 6.6, and 6.4.

Elevated Serum Glucose-6-Phosphate Isomerase Level in Patients with Knee Osteoarthritis
Clinical Laboratory, 2020The present study aims to analyze the serum level of glucose 6-phosphate isomerase (GPI) in patients with knee osteoarthritis (KOA) and evaluate its value in the diagnosis of KOA.One hundred patients with confirmed KOA were selected and 100 healthy people in the same period were selected as the control group.

Molecular basis for the isozymes of bovine glucose-6-phosphate isomerase
Archives of Biochemistry and Biophysics, 1988Glucose-6-phosphate isomerase exists as multiple, catalytically active isozymes which can be resolved by polyacrylamide gel electrophoresis, isoelectric focusing, and ion-exchange chromatography. GPI from bovine heart was purified to homogeneity and each of the isozymes resolved.

Amoxicillin-Induced Hemolytic Anemia in a Child with Glucose 6-Phosphate Isomerase Deficiency
Annals of Pharmacotherapy, 2010Objective:To describe the first case of amoxicillin-induced nonimmune hemolytic anemia in a child with glucose-6-phosphate isomerase (GPI) deficiency.Case Summary:A 3-year-old boy with GPI deficiency was admitted for upper respiratory tract infection and fever. The patient was treated with a standard dose of amoxicillin (50 mg/kg/day).

We purified recombinant glucose-6-phosphate isomerase from Pyrococcus furiosus using heat treatment and Hi-Trap anion-exchange chromatography with a final specific activity of 0.39 U mg(-1). The activity of the glucose-6-phosphate isomerase for L: -talose isomerization was optimal at pH 7.0, 95 degrees C, and 1.5 mM Co(2+). The half-lives of the enzyme

Ancient diversity of the glucose-6-phosphate isomerase genes
Biochemical Systematics and Ecology, 1995Abstract The DNA and deduced amino acid sequences of the glycolytic enzyme glucose-6-phosphate isomerase (PGI) were analyzed to infer the phyolgenetic relationships among the PGI genes from eukaryotes and prokaryotes. The inferred phylogeny of the PGI genes is at variance with the conventional phylogenetic scheme of the organisms and suggests that (1)

Protein disulphide isomerase assisted folding of human glucose-6-phosphate dehydrogenase
Biochemical Society Transactions, 1995Glucose 6-phosphate dehydrogenase (G6PD) plays a key role to maintain the redox state within the red cells. The molecular basis of human G6PD deficiency rely on the presence of point mutations along its 59.2 kDa subunit [l]. The intracellular active enzyme behave mostly as a homodimer.

The ratios of some key enzymatic activities of carbohydrate metabolism have been measured in human tumor cytosols. The activities of whole hexokinase (low Km, EC 2.7.1.1 and high Km, EC 2.7.1.2), 6-phosphogluconate dehydrogenase (EC 1.1.1.43), glucose-6-phosphate dehydrogenase (EC 1.1.1.49) and glucose-6-phosphate isomerase (EC 5.3.1.9) change ...
