Purine and pyrimidine metabolism.
The pathways of purine biosynthesis and degradation have been elucidated during the last 30 years; the regulation of the mechanisms involved is not yet fully understood, particularly with respect to quantitative aspects. Research into inborn errors of purine metabolism has provided valuable insights into purine synthesis and salvage pathways. Nutrition experiments using purine-free formula diet...

متن کاملPurine and pyrimidine metabolism by estuarine bacteria
Nucleotide bases are ubiquitous in living organisms, but the fate of these compounds in natural environments is poorly understood. Here we studied the metabolism of selected purines and pyrimidines in estuarine bacterial assemblages from the Øresund, Denmark. Depletion of nucleotide bases in the incubations was followed by the appearance of urea. The purine guanine and the catabolic intermediat...
متن کاملPurine and pyrimidine nucleotide metabolism in Mollicutes
Several mollicute genome projects are underway, offering unique opportunities to study genes and metabolic pathways on a genome-wide scale. Here, we have analyzed the conservation and diversity of purine and pyrimidine metabolism in mycoplasmas. An evaluation of discrepancies between genomic analysis and enzymatic data revealed interesting aspects about these organisms. We found important examp...
متن کاملEgf regulates purine and pyrimidine metabolism
It is proposed, Phosphoribosyl Pyrophosphate (PRPP), (product of the pyrimidine biosynthesis key regulative enzyme Phosphoribosylpyrophosphate Synthase-1 (PRPS-1)), accelerates Epidermal Growth Factor (Egf) dependent cells proliferation. However, Egf or its fragments don't have direct impact on the PRPS-1. Reactive Oxygen Species, generated by purine catabolism regulative enzyme Xanthine Oxidor...
