Degradation of purines and pyrimidines by microorganisms 1.1. The ultraviolet-absorption curves of various pyrimidines and purines have been compared before and after submitting to reduction by zinc, by sodium-me... GD Vogels,CVD Drift - 《Bacteriological Reviews》 被引量: 799发表: 1976年 Substr...
The RutR regulon was found to include a large number of genes encoding components for not only degradation of pyrimidines but also transport of glutamate, synthesis of glutamine, synthesis of pyrimidine nucleotides and arginine, and degradation of purines. DNase I footprinting indicated that RutR ...
This enzyme's highest hydrolysis capacity is for uridine, thereby balancing pyrimidine salvage and catabolism. NSH1 was found to be less efficient in the hydrolysis of further nucleosides. However, it remained unclear whether purine nucleosides are processed by NSH1. Moreover, the biochemical and ...
ADP, AMP, IMP) in trained and sedentary subjects before and after maximal physical exercise together with measuring the activity of purine metabolism enzymes as well as the concentration of purine (hypoxanthine, xanthine, uric acid) and pyrimidine (uridine) degradation products in blood. The study ...
Annotation of the C. sticklandii genome reveals that most biosynthetic pathways considered as essential for viability seem to be present (e.g., biosynthesis of amino acids, purines, pyrimidines and cofactors). However, it should be noted that genes involved in synthesis of biotin and pantothenat...
The actin coding sequences are highly similar (>84% nucleotide identity) and have similar CAIs (Figure S4B). A multiple sequence alignment revealed a repeating cytidine tract in the codon wobble position of act42A, act57B and act87E that is interrupted by purines in the non Tst-target ...
plantarum inhibited the activity of xanthine oxidase and purine nucleoside phosphorylase in liver to suppress urate synthesis. The gut microbiota composition did not dramatically change by oral administration of L. plantarum over 14 days, indicated by no significant difference in α and β diversities....
Nucleosides and 3′-nucleotides of purines and pyrimidines were never cleaved even by the crude extracts. 2′-O-methyl-5′-UMP was also resistant to the enzyme reaction.The Km value for 5′-UMP was 6.95×10-3M. Co-factors of low molecular weight were unnecessary for the reaction. ...
Because the metabolism of pyrimidine nucleotides is related to the metabolism of purines, in particular with the cellular concentration of ATP, we decided to investigate the impact of a standardized exercise with increasing intensity on the concentration of uridine, inosine, hypoxanthine, and uric ...
