Abstract
Triosephosphate isomerase (TPI) deficiency (Df) is a rare recessive metabolic disorder that manifests as hemolytic anemia, locomotor impairment, and progressive neurodegeneration. Research suggests that TPI Df mutations, including the "common" TPIE105Dmutation, result in reduced TPI protein stability that appears to underlie disease pathogenesis. Drosophila with the recessive TPIsugarkill allele (a.k.a. sgk or M81T) exhibit progressive locomotor impairment, neuromuscular impairment and reduced longevity, modeling the human disorder. TPIsugarkill produces a functional protein that is degraded by the proteasome. Molecular chaperones, such as Hsp70 and Hsp90, have been shown to contribute to the regulation of TPIsugarkill degradation. In addition, stabilizing the mutant protein through chaperone modulation results in improved TPI deficiency phenotypes. To identify additional regulators of TPIsugarkill degradation, we performed a genome-wide RNAi screen that targeted known and predicted quality control proteins in the cell to identify novel factors that modulate TPIsugarkill turnover. Of the 430 proteins screened, 25 regulators of TPIsugarkill were identified. Interestingly, 10 proteins identified were novel, previously undescribed Drosophila proteins. Proteins involved in co-translational protein quality control and ribosome function were also isolated in the screen, suggesting that TPIsugarkill may undergo co-translational selection for polyubiquitination and proteasomal degradation as a nascent polypeptide. The proteins identified in this study may reveal novel pathways for the degradation of a functional, cytosolic protein by the ubiquitin proteasome system and define therapeutic pathways for TPI Df and other biomedically important diseases.

Abstract
Pyruvate kinase (PKLR) deficiency protects mice and humans against blood-stage malaria. Although mouse strain AcB62 carries a malaria-protective PklrI90N genetic mutation, it is phenotypically susceptible to blood stage malaria induced by infection with Plasmodium chabaudi AS, suggesting a genetic modifier of the PklrI90N protective effect. Linkage analysis in a F2 cross between AcB62 (PklrI90N) and another PK deficient strain CBA/Pk (PklrG338D) maps this modifier (designated Char10) to chromosome 9 (LOD = 10.8, 95% Bayesian CI = 50.7–75Mb). To study the mechanistic basis of the Char10 effect, we generated an incipient congenic line (Char10C) that harbors the Char10 chromosome 9 segment from AcB62 fixed on the genetic background of CBA/Pk. The Char10 effect is shown to be highly penetrant as the Char10C line recapitulates the AcB62 phenotype, displaying high parasitemia following P. chabaudi infection, compared to CBA/Pk. Char10C mice also display a reduction in anemia phenotypes associated with the PklrG338D mutation including decreased splenomegaly, decreased circulating reticulocytes, increased density of mature erythrocytes, increased hematocrit, as well as decreased iron overload in kidney and liver and decreased serum iron. Erythroid lineage analyses indicate that the number of total TER119+ cells as well as the numbers of the different CD71+/CD44+ erythroblast sub-populations were all found to be lower in Char10C spleen compared to CBA/Pk. Char10C mice also displayed lower number of CFU-E per spleen compared to CBA/Pk. Taken together, these results indicate that the Char10 locus modulates the severity of pyruvate kinase deficiency by regulating erythroid responses in the presence of PK-deficiency associated haemolytic anemia.

Abstract
Phosphoglycerate kinase (PGK) deficiency is one of the relatively uncommon causes of hereditary non-spherocytic haemolytic anaemia (HNSHA). The gene encoding the erythrocyte enzyme PGK1, is X-linked. Mutations of this gene may cause chronic haemolysis with or without mental retardation and they may cause myopathies, often with episodes of myoglobinuria, or a combination of these clinical manifestations. Twenty-six families have been described and in 20 of these the mutations are known. The reason for different clinical manifestations of mutations of the same gene remains unknown.

Abstract
Homozygous glucose phosphate isomerase (GPI) deficiency is one of the most important genetic disorders responsible for chronic non-spherocytic hemolytic anemia (CNSHA), a red blood cell autosomal recessive genetic disorder which causes severe metabolic alterations. In this work, we studied a patient with CNSHA due to an 82% loss of GPI activity resulting from the homozygous missense replacement in cDNA position 1040G>A, which leads to substitution of the protein residue A346H mutation. The enzyme is present in a dimeric form necessary for normal activity; the A346H mutation causes a loss of GPI capability to dimerize, which renders the enzyme more susceptible to thermolability and produces significant changes in erythrocyte metabolism.

Abstract
Glucose-6-phosphate dehydrogenase (G6PD) is an enzyme of the pentose phosphate shunt pathway a major function of which is to prevent cellular oxidative damage. Deficiency in red blood cells is associated with a number of varied clinical manifestations. Chronic non-spherocytic haemolytic anaemia is uncommon but is usually characterized by chronic haemolysis, often with severe anaemia. In the past splenectomy in this condition has been thought to be of questionable benefit. We report a case of G6PD Guadalajara where splenectomy produced transfusion independence and have reviewed the literature. Those cases with exon 10 mutations often have a severe clinical phenotype, which responds to splenectomy. This procedure should be considered in this condition.

Abstract
We describe two families with the 'cryohydrocytosis' form of stomatocytosis. Both show a mild stomatocytic anaemia with Hb levels of 12-16 g/dl and reticulocyte counts of 4.3-24%, with very marked autohaemolysis at refrigerator temperatures and pseudohyperkalaemia as a result of loss of K from red cells on storage at room temperature. The ouabain + bumetanide-insensitive 'passive leak' K influx showed a 'U'-shaped temperature dependence, with a minimum at 23 degrees C. In one family, there was consistent variation in haematological severity within the pedigree. In the other, the parents of the proposita were normal, but all three of her children were affected, consistent with a new mutation of a dominant condition. Cold storage of the red cells led to a very marked increase in osmotic fragility and macrospherocytosis, explaining why a diagnosis of 'hereditary spherocytosis' can easily be reached in these pedigrees.

Abstract
Deficiencies in around 20 enzymes, associated with widely different degrees of severity and complexity, have been identified for human erythrocytes. The fact that glycolysis is crucial for erythrocyte function is reflected by the large number of inherited glycolytic enzymopathies. Triosephosphate isomerase (TPI) deficiency, a rare autosomal disease, is usually associated with nonspherocytic hemolytic anemia, progressive neurologic dysfunction, and death in childhood. The two affected Hungarian brothers studied by us have less than 3% TPI activity and enormously (30-50-fold) increased dihydroxyacetone phosphate (DHAP) concentration in their erythrocytes. The well-established concept of the metabolic control theory was used to test the contribution of TPI and some related enzymes to the control of a relevant segment of the glycolytic pathway in normal and deficient cells. Deviation indices, DEJ = (delta J/delta E) E(r)/J(r), which give a good estimation of flux control coefficients using a single large change in enzyme activity, were determined from the fluxes in the absence and presence of exogeneous enzymes. We found that PFK and aldolase are the enzymes that predominantly control the flux, however, the quantitative values depend extensively on the pH: DEJ values are 0.85 and 0.14 at pH 8.0 and 0.33 and 0.67 at pH 7.2 for aldolase and PFK, respectively. Neither the flux rates nor the capacities of the enzymes seem to be significantly different in normal and TPI deficient cells. There is a discrepancy between DHAP levels and TPI activities in the deficient cells. In contrast to the experimental data the theoretical calculations predict elevation in DHAP level at lower than 0.1% of the normal value of TPI activity. Several possibilities suggested fail to explain this discrepancy. Specific associations of glycolytic enzymes to band-3 membrane proteins with their concomitant inactivation have been demonstrated. We propose that the microcompartmentation of TPI that could further decrease the reduced isomerase activity of the deficient cells, is responsible for the high DHAP level.

Abstract
An Italian deficient G6PD variant associated with chronic non-spherocytic haemolytic anaemia (CNSHA) was biochemically characterised and studied at molecular level. Single-strand conformation polymorphism (SSCP) analysis led to the identification of an abnormal migration pattern of an amplified fragment encompassing exons 10 and 11 of the G6PD gene. Sequence analysis of both strands using an automated fluorescent DNA sequencer revealed a G-->A transition at nt. position 1246 in exon 10. A C-->T substitution at nt. 1311 in exon 11 was also found, which has already been described as a silent mutation common in Caucasians. The 1246 G-->A mutation has been described only in a Japanese subject with CNSHA (G6PD Tokyo) not associated with the 1311T polymorphism, suggesting that this mutation may have arisen independently in Europe and Asia.

Abstract
This review delineates the subcellular distribution, biochemical characteristics, and metabolic functions of 5'-nucleotidase (5'NT), summarizes the analytical biochemistry of 5'NT, and assesses the clinical significance of 5'NT determinations in body fluids, cells, and tissues. Salient aspects of the clinical biochemistry of 5'NT, discussed herein, are as follows: (A) Serum 5'NT activity is generally elevated in hepatobiliary diseases, especially with intrahepatic obstruction, but, unlike serum alkaline phosphatase, serum 5'NT activity is not increased in infancy, childhood, pregnancy, or osteoblastic disorders. (B) In cancer patients, elevated serum 5'NT activity does not always indicate hepatobiliary involvement; in some cases, 5'NT may be released into serum from the primary tumor or local metastases. (C) Genetic deficiency of erythrocyte pyrimidine 5'NT activity is a common cause of hereditary non-spherocytic hemolytic anemia. (D) Acquired deficiency of erythrocyte pyrimidine 5'NT activity occurs in patients with beta-thalassemia and lead poisoning. (E) 5'NT activity is low in circulating monocytes, increases markedly upon their differentiation to tissue macrophages, and subsequently diminishes during macrophage activation. (F) Lymphocyte ecto-5'NT activity, a plasma membrane marker of cell maturation, is generally low in immunodeficiency states, and undergoes characteristic changes in patients with certain lymphomas and leukemias.

Abstract
Enzymatic and electron microscopical studies were performed on the muscle of a proband with phosphofructokinase deficiency. Enzymatic studies showed that muscle phosphofructokinase activity of the proband was decreased to about a half of normal. This enzyme was quite thermolabile and had low affinity for fructose 6-phosphate. Electron microscopical studies showed the accumulation of glycogen granules beneath the sarcolemma and between the myofibrils in spite of a lack of accumulation of the intermediates before the step of phosphofructokinase. The proband's clinical symptoms, i.e., hemolytic anemia and myopathy, were considered to be due to the unstable, mutant, muscle-type phosphofructokinase in the red blood cells and muscle.

Abstract
Radioisotope studies of bilirubin turnover, ferrokinetics, and red cell survival ((51)Cr) in a patient with erythrocyte PK deficiency have provided evidence for prompt reticulocyte sequestration and destruction by the reticuloendothelial system. More mature erythrocytes appeared to survive well despite their deficiency of PK. PK-deficient reticulocytes, dependent upon oxidative phosphorylation for ATP production, are exquisitely sensitive to cyanide- or nitrogen-induced mitochondrial inhibition. If oxidative phosphorylation is unavailable, ATP levels decline rapidly, producing alterations in the cell membrane which allow massive losses of potassium and water. The result is a shrunken, spiculated, viscous cell whose rheologic properties would favor its sequestration by the reticuloendothelial system. Those reticulocytes with particularly low levels of PK exhibit very low glycolytic rates and thus are uniquely reliant upon oxidative phosphorylation. Other reticulocytes, better endowed with PK activity, can meet the increased ATP requirements of young erythrocytes. Upon reaching maturity, such cells have diminished ATP needs and can, therefore, survive despite their enzyme deficiency.

Abstract
Erythrocyte pyruvate kinase (PK) activity was determined by the lactate dehydrogenase-coupled spectrophotometric assay. The effects of modifications in the buffer and in substrate concentrations were studied. Three patients with congenital non-spherocytic hemolytic anemia were deficient in erythrocyte PK, and were evidently homozygous for this deficiency. The daughter of one patient and the parents of another had intermediate PK levels and were probably heterozygous. The erythrocyte adenosine triphosphate (ATP) level was low in one patient, high in another. Adenosine triphosphatase activity of the erythrocyte membranes of one patient was normal.

Abstract
A family with congenital non-spherocytic hemolytic anemia associated with glucose-6-phosphate dehydrogenase (G6PD) deficiency was studied. Two females, heterozygous for the enzyme deficency, had evidence of a hemolytic anemia. The results of chromium-51 erythrocyte life span studies prior to, during, and after periods of primaquine administration suggested that the hemolytic anemia in these women was due to the presence of two populations of red blood cells in their circulation. One population had normal G6PD levels and a normal life span, whereas the other had diminished enzyme activity and a shortened life span.In vitro metabolic studies of the erythrocytes of a heterozygous female and a hemizygous male suggested that, in spite of G6PD deficiency, the synthesis and breakdown of adenosine triphosphate and 2,3-diphosphoglyceric acid was similar to that in normal erythrocytes.
