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 ...

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

Cell age dependent decay of human erythrocytes glucose-6-phosphate isomerase
BBA - Proteins and Proteomics, 1989Glucose-6-phosphate isomerase shows a biphasic decay pattern during red blood cell aging, which is very fast during the first part of cell's life span in circulation. This decay is not due to accumulation of inactive enzyme molecules, as shown by immunological studies, but is accompanied by the formation of secondary isozymes (i.e., chemically modified

Glucose-6-phosphate isomerase deficiency-Nahariya: extreme in vitro and in vivo lability of the mutant enzyme. [PDF]
Israel journal of medical sciences, 1984 A glucose-6-phosphate isomerase deficiency is described in an Arab boy suffering from chronic hemolytic anemia. The patient was probably true homozygous for the defect. The residual enzyme activity in his red blood cells (RBC) was approximately 30% of normal. The most striking enzyme abnormality observed was an extreme heat lability: upon incubation at

Leishmania mexicana mexicanaglucose-6-phosphate isomerase: crystallization, molecular-replacement solution and inhibition [PDF]
Acta Crystallographica Section D: Biological Crystallography, 2004 Glucose-6-phosphate isomerase (PGI; EC 5.3.1.9; also often called by its old nomenclature phosphoglucose isomerase) is an intracellular enzyme that catalyses the reversible conversion of D-glucose 6-phosphate (G6P) to D-fructose 6-phosphate (F6P).

Glucose - 6 - phosphate isomerase
Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1981Abstract Glucose-6-phosphate isomerase (EC 5 . 3 .1 .9) is a dimeric enzyme of molecular mass 132000 which catalyses the interconversion of D-glucose-6-phosphate and D-fructose- 6-phosphate. The crystal structure of the enzyme from pig muscle has been determined at a nominal resolution of 2.6 A. The structure is of the a/B type.

Anomerization of glucose 6-phosphate: Catalysis by phosphoglucose isomerase
Archives of Biochemistry and Biophysics, 1979Abstract The anomerase (1-epimerase) activity of phosphoglucose isomerase ( d -glucose 6-phosphate ketol-isomerase EC 5.3.1.9) has been studied. The pH-Vmax profile, assayed by two different methods, shows a dependence on two ionizable groups in the enzyme with pK values of 7.0 and 9.3 at 0 °C.

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.

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.

Diagnostic value of glucose-6-phosphate isomerase in rheumatoid arthritis
Clinica Chimica Acta, 2010Although glucose-6-phosphate isomerase (G6PI), anti-G6PI antibodies and G6PI-containing immune complexes (G6PI-CIC) have proved high expression in patients with rheumatoid arthritis (RA), comprehensive evaluation of the G6PI-derived markers, G6PI antigen, anti-G6PI Abs, G6PI-CIC and G6PI mRNA, in the diagnosis of RA remains necessary.We measured G6PI ...
