BMC Plant Biology, 2018 Background The ureides allantoin and allantoate are major metabolic intermediates of purine catabolism with high nitrogen-to-carbon ratios. Ureides play a key role in nitrogen utilization in ureide-type legumes, but their effects on growth and ...

Recueil des Travaux Chimiques des Pays-Bas, 1969 AbstractThe rate of hydrolysis of allantoate (diureidoacetate) was measured as a function of temperature and pH. Similar experiments were performed with urea and N‐carbamoylglycine (hydantoate) and the results were compared. At pH values below 7 allantoate was converted to ureidoglycolate and urea.

RNA Catabolites Contribute to the Nitrogen Pool and Support Growth Recovery of Wheat [PDF]
Frontiers in Plant Science, 2018 Turn-over of RNA and catabolism of nucleotides releases one to four ammonia molecules; the released nutrients being reassimilated into primary metabolism.

Purification and Characterization of Allantoate Amidohydrolase fromBacillus fastidiosus
Archives of Biochemistry and Biophysics, 1995 Allantoate amidohydrolase from Bacillus fastidiosus was purified 170-fold to homogeneity as judged by isoelectric focusing and nondenaturing and sodium dodecyl sulfate polyacrylamide gel electrophoresis. The molecular mass was estimated to be 128 kDa. The enzyme appeared to be a homodimer with a subunit molecular mass of 66 kDa.

Enzymes and cellular interplay required for flux of fixed nitrogen to ureides in bean nodules. [PDF]
Nat Commun, 2022 Tropical legumes transport fixed nitrogen in form of ureides (allantoin and allantoate) over long distances from the nodules to the shoot. Ureides are formed in nodules from purine mononucleotides by a partially unknown reaction network that involves ...

Red Blood Cell Metabolism in Patients with Propionic Acidemia
Separations, 2021 Propionic acidemia (PA) is a rare autosomal recessive disorder with an estimated incidence of 1:100,000 live births in the general population. Due in part to an insufficient understanding of the disease’s pathophysiology, PA is often associated with ...

Combined genomics to discover genes associated with tolerance to soil carbonate
Plant, Cell &Environment, Volume 46, Issue 12, Page 3986-3998, December 2023., 2023 Abstract Carbonate‐rich soils limit plant performance and crop production. Previously, local adaptation to carbonated soils was detected in wild Arabidopsis thaliana accessions, allowing the selection of two demes with contrasting phenotypes: A1 (carbonate tolerant, c+) and T6 (carbonate sensitive, c−).

New Phytologist, Volume 240, Issue 2, Page 744-756, October 2023., 2023 Summary Nitrogen‐fixing symbioses allow legumes to thrive in nitrogen‐poor soils at the cost of diverting some photoassimilate to their microsymbionts. Effort is being made to bioengineer nitrogen fixation into nonleguminous crops. This requires a quantitative understanding of its energetic costs and the links between metabolic variations and symbiotic
