Glucose - 6 - phosphate isomerase

Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1981
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.

A Novel Glucose 6-Phosphate Isomerase from Listeria monocytogenes

The Protein Journal, 2014
D-Arabinose 5-phosphate isomerases (APIs) catalyze the interconversion of D-ribulose 5-phosphate and D-arabinose 5-phosphate (A5P). A5P is an intermediate in the biosynthesis of 3-deoxy-D-manno-octulosonate (Kdo), an essential component of lipopolysaccharide, the lipopolysaccharide found in the outer membrane of Gram-negative bacteria.

Anomerization of glucose 6-phosphate: Catalysis by phosphoglucose isomerase

Archives of Biochemistry and Biophysics, 1979
Abstract 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.

Diagnostic value of glucose-6-phosphate isomerase in rheumatoid arthritis

Clinica Chimica Acta, 2010
Although 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 ...

Mouse glucose-6-phosphate isomerase and neuroleukin have identical 3′ sequences

Nature, 1988
Neuroleukin is a neurotrophic factor of relative molecular mass (Mr) 56,000 (56K) found in skeletal muscle, brain, heart and kidneys which supports the survival of embryonic spinal neurones, skeletal motor neurones and sensory neurones. Neuroleukin is also a lymphokine product of lectin-stimulated T cells and induces immunoglobulin secretion by ...

Combined Erythrocyte Phosphohexose Isomerase and Glucose-6-Phosphate Dehydrogenase Deficiency

Human Heredity, 1973
Combined erythrocyte phosphohexose isomerase (PHI) and glucose-6-phosphate dehydrogenase (G6PD) deficiency without hemolytic crisis is reported in a Thai family. The propositus (a male), heterozygous for PHI deficiency and hemizygous for G6PD deficiency, has a PHI activity of about half of the normal.

Cell age dependent decay of human erythrocytes glucose-6-phosphate isomerase

Biochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology, 1989
Glucose-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

Ancient diversity of the glucose-6-phosphate isomerase genes

Biochemical Systematics and Ecology, 1995
Abstract 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)

Purification and characterization of glucose-6-phosphate isomerase from Bacillus stearothermophilus

Archives of Biochemistry and Biophysics, 1971
Abstract 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, 1986
Glucose-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.
