Metabolism and Ecology of Purine Alkaloids
Frontiers in Bioscience, 2006In this review, the biosynthesis, catabolism, ecological significance, and modes of action of purine alkaloids particularly, caffeine, theobromine and theophylline in plants are discussed. In the biosynthesis of caffeine, progress has been made in enzymology, the amino acid sequence of the enzymes, and in the genes encoding N-methyltransferases.

Pathophysiology of Purine Metabolism in Man
Enzyme, 2017In this review, some of the more recent concepts related to the pathophysiology of purine metabolism in man have been reviewed. Despite the concerted effort of a number of investigators, however, many questions remain unanswered. Hopefully, new clues will be unraveled as clinical and basic scientists continue to embark into may areas in the field which

Disorders of purine and pyrimidine metabolism
Molecular Genetics and Metabolism, 2005The disorders of purine and pyrimidine metabolism are unusual in their variety of clinical presentations and in the mechanisms by which these presentations result from the fundamental mutations. In the most common of the hyperuricemic metabolic disorders, deficiency of hypoxanthine phosphoribosyl transferase, the fundamental deficiency in the activity ...

Purine Metabolism in Rat Macrophages
1984The association of deficiencies of purine metabolic enzymes with immunodeficiency diseases has stimulated research in purine metabolism of lymphoid cells. Up to now our knowledge about purine metabolism of other cells of the immune system, e.g., macrophages, is relatively limited.

Immunological Aspects of Purine Metabolism
1977The development of our knowledge of the immune system has been reviewed and evidence presented of the need for a rapid rate of purine synthesis de novo for the proliferative events in this process. The mechanism of the inhibition of the immune system in a model of ADA deficiency has been studied intensively and considerable indirect evidence obtained ...

Nutritional State and Purine Metabolism
1977Hyperuricemia and gout are multifarious disorders of purine metabolism with heredity as genetic base and exogenic environmental factors which are prevailing of alimentary nature including overcaloric and fatty nutrition and alcohol consumption. These latter factors may be able to induce the manifestation of clinical gout.
