Pyruvate kinase deficiency

Clinical Biochemistry, 1990
Pyruvate kinase (PK) deficiency was initially described by Valentine et al. in 1961. Since then, more than 300 cases have been described, including 65 in Japan. PK deficiency is the most common hereditary nonspherocytic hemolytic anemia among several red cell enzyme defects of the Embden-Meyerhof glycolytic pathway.

Defective erythrocyte pyruvate kinase

Clinica Chimica Acta, 1976
A defective pyruvate kinase (EC 2.7.1.40) is described. The abnormal PK is characterized by a shift in the R in equilibrium T equilibrium to the T-state. The Ko.5 for the substrate phosphoenol pyruvate is about 6 times higher than for the normal enzyme, while the KM value for the positive effector Fru-1, 6-P2 is increased.

“Fluorokinase” and pyruvic kinase

Archives of Biochemistry and Biophysics, 1958
Abstract 1. 1. The enzyme catalyzing the CO2-dependent phosphorylation of fluoride by adenosine triphosphate to yield monofluorophosphate, an activity referred to as “fluorokinase,” has been isolated in crystalline form from rabbit muscle extracts. The crystalline enzyme has been found to possess considerable pyruvic kinase activity. 2. 2.

Mutations in pyruvate kinase

Human Mutation, 1996
Pyruvate kinase (PK) deficiency due to mutations of the PKLR gene is a common cause of hereditary nonspherocytic hemolytic anemia. Thus far, 55 different mutations have been described in patients with PK-deficient hemolytic anemia. Polymorphisms within the PKLR gene and in the tightly linked glucocerebrosidase (GBA) gene suggest that PK deficiency may ...

Pyruvate kinase electrophoresis in normal and pyruvate kinase deficient hemolysates

Clinica Chimica Acta, 1974
Abstract Two bands of pyruvate kinase activity were demonstrated in normal hemolysates with high voltage electrophoresis at pH 5.3 using cellulose acetate strips. Heterozygotes with red cell pyruvate kinase deficiency also exhibited two bands. Six of ten homozygous patients showed two bands, the remaining four only one band.

Regulation of pyruvate kinase

Advances in Enzyme Regulation, 1969
Abstract The mechanism and sequence of events of the induction of liver pyruvate kinase by sucrose and fructose administration were examined. Actinomycin and cycloheximide prevented the sucrose and fructose induced rise in pyruvate kinase activity.
