Pyruvate Kinase Deficiency Causing Priapism
Case Reports in Hematology, 2023 Pyruvate kinase deficiency (PKD) is an autosomal recessive defect of the enzyme pyruvate kinase (PK) which is involved in catalyzing a reaction that produces ATP in the glycolytic pathway. It is the most common defect of the glycolytic pathway associated

The allosteric regulation of pyruvate kinase [PDF]
FEBS Letters, 1996 Crystallographic and mutagenesis studies have unravelled the general features of the allosteric transition mechanism in pyruvate kinase. The enzyme displays a dramatic conformational change in going from the T‐ to the R‐state. All three domains forming each subunit of the tetrameric enzyme undergo simultaneous and concerted rotations, in such a way ...

Minimizing acetate formation in E. coli fermentations [PDF]
, 2007 Escherichia coli remains the best established production organisms in industrial biotechnology. However, during aerobic fermentation runs at high growth rates, considerable amounts of acetate are accumulated as by-product.

Pyruvate Kinase M2 and Cancer: The Role of PKM2 in Promoting Tumorigenesis
Frontiers in Oncology, 2020 Pyruvate kinase plays a pivotal role in regulating cell metabolism. The final and rate-limiting step of glycolysis is the conversion of Phosphoenolpyruvate (PEP) to Pyruvate, which is catalyzed by Pyruvate Kinase. There are four isomeric, tissue-specific

The contribution of two isozymes to the pyruvate kinase activity of Vibrio cholerae: One K+-dependent constitutively active and another K+-independent with essential allosteric activation. [PDF]
PLoS ONE, 2017 In a previous phylogenetic study of the family of pyruvate kinase EC (2.7.1.40), a cluster with Glu117 and another with Lys117 were found (numbered according to the rabbit muscle enzyme).

Pyruvate Kinase Revisited [PDF]
Journal of Biological Chemistry, 2005 Desde hace más de 50 años, se sabe que el K+ es un activador esencial de la piruvato quinasa (Kachmar, J. F., y Boyer, P. D. (1953) J. Biol. Chem. 200, 669-683). Sin embargo, el papel de K+ en la catálisis por piruvato quinasa no se ha entendido completamente.

Hydrops fetalis associated with erythrocyte pyruvate kinase deficiency [PDF]
, 2000 The authors report a case of hydrops fetalis due to severe pyruvate kinase deficiency, the most unusual clinical manifestation of this disease. Conclusion Pyruvate kinase deficiency, as other erythrocyte enzymopathies, must be considered in the ...

Phosphoenolpyruvate Carboxykinase Is Involved in the Decarboxylation of Aspartate in the Bundle Sheath of Maize [PDF]
, 1999 We recently showed that maize (Zea mays L.) leaves contain appreciable amounts of phosphoenolpyruvate carboxykinase (PEPCK; R.P. Walker, R.M. Acheson, L.I. Técsi, R.C. Leegood [1997] Aust J Plant Physiol 24: 459–468).
