Patterns of purine nucleotides in fish erythrocytes

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1979
1. The purine nucleotides were determined in the whole blood of 9 fresh water teleosts and 2 marine selachians. 2. GTP and ATP accounted for 88-99% of the total erythrocytes purines. 3. The ATP/ADP ratio ranged from 11 to 60 in the erythrocytes of the fish examined. 4.

Activation of aspartate transcarbamoylase by purine nucleotides

Biochimica et Biophysica Acta (BBA) - Enzymology, 1970
Abstract 1. 1. A previous report demonstrated an increase in aspartate transcarbamoylase activity (carbamoylphosphate: l -aspartate carbamoyltransferase, EC 2.1.3.2) upon incubation of an homogenate of Escherichia coli with ATP, GTP, phosphoenolpyruvate, amino acids and magnesium acetate.

Purine Nucleotide Restoration in HPRT- Cells

1989
Lesch-Nyhan syndrome is caused by a deficiency of the enzyme hypoxanthine-guanine phosphoribosyltransferase (HPRT) (1, 2). This enzyme catalyzes the conversion of the purine bases hypoxanthine and guanine to their respective 5′ribo-nucleotides. It is reasonable to assume that a deficiency of HPRT would cause a decrease in the cellular concentrations of

Purine Nucleotide Imbalance in Immunodeficiency Disorders

1985
In 1972, Dr Hilaire Meuwissen of Albany, New York, sent some blood samples to Eloise Giblett of the Puget Sound Blood Center, Seattle, Washington, for analysis of genetic markers. One of the blood samples was from a patient with severe combined immunodeficiency disease and the other samples were from the patient’s parents Dr.
