Many plants, fungi, and bacteria catabolize allantoin as a mechanism for nitrogen assimilation. Recent reports have shown that in plants and some bacteria the product of hydrolysis of allantoin by allantoinase is the unstable intermediate ureidoglycine. While this molecule can spontaneously decay, genetic analysis of some bacterial genomes indicates that an aminotransferase may be present in the pathway. Here we present evidence that Klebsiella pneumoniae HpxJ is an aminotransferase that…

Alternative conformation induced by substrate binding for Arabidopsis thalianaN6-methyl-AMP deaminase
Structural studies provide the first look of this important metabolic enzyme and shed lights on its catalytic pathway, which holds promise for the structure-based drug design for MAPDA-related diseases.
Ureide metabolism in plant-associated bacteria: purine plant-bacteria interactive scenarios under nitrogen deficiency
Given widespread concerns for crop losses due to the drastically changing climate and prevailing agricultural practices, the understanding of the interactive signaling for the purine metabolisms between PAB and plants takes on a major importance, as it may support management decisions necessary to maintain PAB biodiversity and the agricultural services provided by PAB to crops.
Identifying reaction modules in metabolic pathways: bioinformatic deduction and experimental validation of a new putative route in purine catabolism
Using the reaction module concept to define at least two successive steps catalyzed by homologous enzymes in pathways alignable by similar chemical reactions will help to trace how the primordial promiscuous enzymes were assembled progressively in functional modules, as the present pathways diverged from ancestral pathways to give birth to the present-day mechanistically diversified superfamilies.
The Multidrug Efflux System AcrABZ-TolC Is Essential for Infection of Salmonella Typhimurium by the Flagellum-Dependent Bacteriophage Chi
The importance of a multidrug efflux pump for the infection of Salmonella enterica by a flagellotropic phage is discovered and coadministering antibiotics and flagella-dependent phage may be a particularly potent antibacterial therapy.
Caracterización molecular del metabolismo del alantoato en judía (Phaseolus Vulgaris)

The purinosome, a multi-protein complex involved in the de novo biosynthesis of purines in humans.
The most recent discoveries relating to purine biosynthesis are discussed, with particular emphasis upon the dynamic multi-protein complex called the purinosome and the attempts made to exploit this knowledge for drug discovery.


Ureide catabolism in Arabidopsis thaliana and Escherichia coli.
Two enzymes are identified that catalyze the final reactions of purine degradation in the model plant Arabidopsis thaliana and an alternative metabolic route via ureidoglycine transaminase can be predicted for other organisms.
Chemical basis of nitrogen recovery through the ureide pathway: formation and hydrolysis of S-ureidoglycine in plants and bacteria.
NMR evidence is reported that the true product of the AAH reaction is S-ureidoglycine, a nonstandard alpha-amino acid that spontaneously releases ammonia in vitro, strengthening the basis for the known sensitivity of the ureide pathway to Mn availability and suggesting a further rationale for the active transport of Mn in the endoplasmic reticulum of plant cells.

A systematic analysis of the gene cluster was undertaken to identify genes involved in allantoin utilization, and the products of these genes were overexpressed and shown to have the predicted corresponding enzyme activities.
Completing the uric acid degradation pathway through phylogenetic comparison of whole genomes
Through phylogenetic genome comparison, this work identifies here two genes that share with urate oxidase a common history of loss or gain events and shows that the two proteins encoded by mouse genes catalyze two consecutive steps following urate oxidation to 5-hydroxyisourate (HIU): hydrolysis of HIU and decarboxylation of OHCU to give S-allantoin.
