A hexokinase preparation was obtained from aSaccharomyces cereviaiae mutant strain deficient in glucosephosphate isomerase (GPI) and mannosephosphate isomerase (MPI) by precipitation with ammonium sulfate. The supernatant fraction corresponding to 40 - 60 % saturation showed the lowest content in GPI and MPI activity. The fraction was used without further purification in the determination of glucose, either free or in a mixture with fructose and mannose. The results were similar to those obtained with pure commercial hexokinase.
Glucose phosphate isomerase (GPI) deficiency with severe haemolysis and hydrops fetalis was found in the first child of unrelated, healthy Caucasian parents. The child died at 3 hours. Both parents were found to have 50% of normal red cell GPI activity and qualitative tests on their red cells and white cells showed that each was heterozygous for a different GPI variant allele associated with enzyme deficiency. Tests on the placenta showed that the propositus was a compound heterozygote. Examination of amniotic cells obtained by amniocentesis on the mother at 28 weeks in her second pregnancy led to the prenatal diagnosis of GPI deficiency. This second child, a compound heterozygote at the GPI locus indistinguishable from the first, was successfully treated by immediate exchange transfusion and subsequent blood transfusions.

N2 - Disruption of the gene pgi1 of Saccharomyces cerevisiae, which codes for phosphoglucose isomerase, results in a dramatic increase in the amount of intracellular glycogen in early exponential cultures. The level or glucose 6-phosphate was much higher in mutant than in wild-type cells. Phosphorylase a activity and the state of activation of glycogen synthase were also investigated. Phosphorylase a activity was rather low along the culture in wild-type cells, whereas it was consistently higher in mutants. Glycogen synthase was mostly in the active form in early-medium exponential cultures in wild-type cells whereas the activation state of this enzyme in mutant cells, ...
1G98: Crystal structure of rabbit phosphoglucose isomerase complexed with 5-phospho-D-arabinonate identifies the role of Glu357 in catalysis.
DNA was isolated from four unrelated glucose phosphate isomerase-deficient patients. Seven new mutations in the coding region were found: 247 C--,T, 671 C--,T, 818 G--,A, 833 C--,T, 1039 C--,T, 1459 C--,T, and 1483 G--,A. Three patients were compound heterozygotes, and one patient was a homozygote of 247 C--,T/247 C--,T. Six mutations were found to involve highly conserved amino acids of glucose phosphate isomerase, suggesting that these residues are crucial for the maintenance of biological activity. Two polymorphic sites were also identified, 489 A--,G and 1356 G--,C, which do not produce a change in the amino acid sequence. ...
How cellular respiration can be sped up or slowed down. The free energy released in this process is used as ATP and NADP. Glucose-6-phosphate is isomerised to fructose-6-phosphate by phosphohexose isomerase. Stimulation of glycolysis by placing tubers in an atmosphere of nitrogen led to significant declines in their contents of fructose-6-phosphate and phosphoenolpyruvate. In the fifth step, an isomerase transforms the dihydroxyacetone-phosphate into its isomer, glyceraldehyde-3-phosphate. The fourth step in glycolysis employs an enzyme, aldolase, to cleave 1,6-bisphosphate into two three-carbon isomers: dihydroxyacetone-phosphate and glyceraldehyde-3-phosphate. How many steps are in glycolysis and what are they? The glycolytic pathway is a major metabolic pathway for microbial fermentation which involves the catabolism of glucose into pyruvate. Steps 1 and 3 = - 2ATP Steps 7 and 10 = + 4 ATP Net visible ATP produced = 2. 4. Only three steps produce a large decrease in free energy, meaning ...

Glucose-6-phosphate isomerase (GPI) (EC 5.3.1.9) or phosphoglucose isomerase (PGI) [1,2] is a dimeric enzyme that catalyzes the reversible isomerization of glucose-6-phosphate and fructose-6-phosphate. PGI is involved in different pathways: in most higher organisms it is involved in glycolysis; in mammals it is involved in gluconeogenesis; in plants in carbohydrate biosynthesis; in some bacteria it provides a gateway for fructose into the Entner-Doudouroff pathway. Besides its role as a glycolytic enzyme, mammalian PGI can function as a tumor-secreted cytokine and an angiogenic factor (AMF) that stimulates endothelial cell motility. Mammalian PGI is also neuroleukin [3], a neurotrophic factor which supports the survival of various types of neurons. The sequence of PGI is conserved among diverse species ranging from bacteria to mammals and structures form a similar fold (see ,PDB:1IAT,) [4,5], comprised of two subdomains that each form an α-β-α sandwich, with the active site located in the ...

We previously concluded that selective sweeps could not account for the reduced diversity in L. uniflora populations (Liuet al. 1998), on the basis of the finding of different alleles in different populations. It is now clear, however, that the populations studied represent two different species, L. uniflora and L. torulosa. Low diversity, without between-population differences, as in the two L. uniflora populations studied, could be explained by either hitchhiking or bottlenecks. In either interpretation, many loci in the genome should be similarly affected and have low diversity. This is, in fact, the case for several loci (Liu 1998).. Selective sweeps should certainly be considered a possibility, because the evolutionary loss of self-incompatibility in the selfing taxa must have involved hitchhiking events while the gene causing selfing was spreading through the populations. In an outcrosser, or in partially selfing populations such as L. crassa, a hitchhiking event at one locus would almost ...

Five alleles representing three electromorphs of phosphoglucose isomerase (PGI) have been transferred from natural isolates of E. coli into the genetic background of E. coli K12 and examined for their effect on growth rate in chemostats limited for glucose or fructose. With glucose limitation, all alleles are selectively neutral or nearly neutral within the limit of resolution of the technique, whether the genetic background is nonmutant or whether it contains a deletion of the locus of glucose-6-phosphate dehydrogenase, the enzyme that provides an alternative metabolic pathway for the substrate of PGI. With fructose limitation, one of the naturally occurring alleles has a small but reproducible detrimental effect on growth rate. A kinetic difference in this detrimental allozyme, apparently relating to an inhibition constant, has been observed in some, but not all, lots of substrate, and a similar difference has also been noted in one of the rare electromorphs that could not be transferred into ...

Glucose phosphate broth is used to perform Methyl Red (MR) test and Voges Proskauer (VP) test. Glucose - 5 g/l Dipotassium phosphate - 5 g/l Proteose Peptone - 5 g/l Distilled water - 1000 ml pH - 6.9 Principle: It is used to determine the ability of an organism to produce mixed acids by fermentation of glucose and to overcome the buffering capacity of the medium. Inoculate MacConkeys (Glucose phosphate broth) with pure culture of test organism. Incubate the broth at 35 °C for 48-72 hours. After incubation add 5 drops of Methyl Red directly into the broth, through the sides of the tube. The development of stable red color in the surface of the medium indicates sufficient acid production to lower the pH to 4.4 and constitute a positive test. Since other organism may produce lesser quantities of acid from the test substrate, an intermediate orange color between yellow and red may develop. This does not indicate positive test. Positive and negative controls should be run after preparation of each ...

AU - Londesborough, John. AU - Penttilä, Merja. PY - 2002/11/19. Y1 - 2002/11/19. N2 - Deletion of the phosphoglucose isomerase gene, PGI1, in Saccharomyces cerevisiae leads to a phenotype for which glucose is toxic. This is related to overproduction of NADPH through the oxidative part of the pentose phosphate pathway and the incompetence of S. cerevisiae to deal with this overproduction. A similar deletion (rag2) in Kluyveromyces lactis does not lead to such a phenotype. We transformed a genomic library of K. lactis in a yeast vector to a S. cerevisiae strain with a pgi1 deletion and screened for growth on glucose. We found a gene (GDP1) which encodes a phosphorylating glyceraldehyde-3-phosphate dehydrogenase, NADP-GAPDH (EC 1.2.1.13), that accepts both NADP and NAD. This is the first report of a eukaryotic, nonplant, ...

The analysis of midgestation chimaeras, by electrophoretic separation of glucose phosphate isomerase (GPI) isozymes, showed that ES cells were capable of colonizing trophectoderm and primitive endoderm derivatives at a low frequency, as well as producing a high rate of chimaerism in tissues of the fetus and extraembryonic mesoderm.. ...
FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The protein encoded by this gene is an isozyme of phosphoglucomutase (PGM) and belongs to the phosphohexose mutase family. There are several PGM isozymes, which are encoded by different genes and catalyze the transfer of phosphate between the 1 and 6 positions of glucose. In most cell types, this PGM isozyme is predominant, representing about 90% of total PGM activity. In red cells, PGM2 is a major isozyme. This gene is highly polymorphic. Mutations in this gene cause glycogen storage disease type 14. Alternativley spliced transcript variants encoding different isoforms have been identified in this gene.[provided by RefSeq, Mar 2010 ...

The hallmark of rheumatoid arthritis (RA) is specific destruction of the synovial joints. In a mouse line that spontaneously develops a disorder with many of the features of human RA, disease is initiated by T cell recognition of a ubiquitously expressed self-antigen; once initiated, pathology is driven almost entirely by immunoglobulins. In this study, the target of both the initiating T cells and pathogenic immunoglobulins was identified as glucose-6-phosphate isomerase, a glycolytic enzyme. Thus, some forms of RA or related arthritides may develop by a mechanism fundamentally different from the currently popular paradigm of a joint-specific T cell response. ...
However, it is important to note that the decrease in GPi activity found by Chiken and Nambu (2013) in healthy monkeys may not entirely reflect the DBS mechanism underlying ameliorative effects in Parkinsons disease (PD). Chiken and Nambu (2013) argue that in PD, increased GPi GABAA receptor expression would amplify, not counteract, their effect. Nevertheless, results have been reported using a PD monkey model that may not support this conclusion. First, the efficacy of GPi GABA transporters (critical for GABA transmission) is altered in a PD model (Galvan et al., 2010), which may implicate different GPi-DBS effects in PD. Second, GPi electrical stimulation in a PD model resulted in multiphase responses of GPi neurons (McCairn and Turner, 2009), as opposed to the inhibition (only) in healthy monkeys reported by Chiken and Nambu (2013). Therefore, factors in addition to GABAA overexpression may be relevant to the DBS effect in PD, and may explain these inconsistent results between GPi ...
