Studies on pyruvate kinase deficiency, pyrimidine 5-'nucleotidase deficiency and adenosine deaminase overproduction
Abstract:
Using recently established ICSH recommended methods, red cell pyruvate kinases (PK) of 20 patients with PK deficiency were characterized and 7 new PK variants were found. Analysis of partially purified red cell pyrimidine 5'-nucleotidase (P5N) from a patient with P5N deficiency provided the evidence for a structural alteration of the enzyme protein. Red cell adenosine deaminase (ADA) from a patient with 40-fold increase in ADA activity associated with hemolytic anemia was purified and compared with that from normal subjects. It is most conceivable that the increased ADA activity represents increased amount of structurally normal enzyme.

Fates of Pyruvate
In aerobic organisms, pyruvate is metabolized via the citric acid cycle to produce reduced coenzymes NADH and FADH2. These coenzymes are then oxidized in the electron transport chain to produce ATP and, in the process, regenerate the NAD+ and FAD. As seen in some cell types and organisms, fermentation...
Allosteric Proteins-ATCase
Aspartate transcarbamoylase (ATCase) is a cytosolic enzyme that catalyzes the condensation of L-aspartate and carbamoyl phosphate to N-carbamoyl-L-aspartate. This reaction is the first step in pyrimidine biosynthesis. UTP and CTP, the end products of the pyrimidine synthesis pathway,...
