Plant nucleoside N‐ribohydrolases: riboside binding and role in nitrogen storage mobilization

open access: yesThe Plant Journal, Volume 117, Issue 5, Page 1432-1452, March 2024.
Significance Statement Plant nucleoside N‐ribohydrolases (NRHs), studied in low and high plants (moss and maize) recognize and hydrolyze purine, cytokinin, and pyrimidine nucleosides through water interactions with the base as shown by X‐ray crystallography.

Chemical Basis of Nitrogen Recovery through the Ureide Pathway: Formation and Hydrolysis of S-Ureidoglycine in Plants and Bacteria

open access: yes, 2016
While some organisms, including humans, eliminate oxidized purines to get rid of excess nitrogen, for many others the recovery of the purine ring nitrogen is vital.

Gut Microbiota and Metabolic Syndrome: Relationships and Opportunities for New Therapeutic Strategies

open access: yesScientifica, Volume 2024, Issue 1, 2024.
Since its discovery, numerous studies have shown the role of the microbiota in well‐being and disease. The gut microbiota represents an essential factor that plays a multidirectional role that affects not just the gut but also other parts of the body, including the brain, endocrine system, humoral system, immune system, and metabolic pathways, as well ...

Molecular and functional characterization of allantoate amidohydrolase from Phaseolus vulgaris

open access: yes
Embargado hasta 01/01/2100Allantoate degradation is an essential step for recycling purine-ring nitrogen in all plants, but especially in tropical legumes where the ureides allantoate and allantoin are the main compounds used to store and transport the

Marsupial with an Allantoic Placenta

open access: yesNature, 1896
I HAVE just received from my friend and former pupil Mr. J. P. Hill, Demonstrator of Biology in the Sydney University, an advanced copy of the Abstract of Proceedings of the Linnean Society of New South Wales for November 27, in which he announces the discovery of a true allantoic and highly vascular placenta, of a discoidal and most probably deciduous

UREIDE ACCUMULATION DURING ABIOTIC STRESS IN LEGUMES [PDF]

open access: yes, 2016
Allantoin and allantoate, ureides formed during the catabolism of purines, accumulate in plant tissue in response to drought and other abiotic stresses.

Characterization of the gene cluster involved in allantoate catabolism and its transcriptional regulation by the RpiR-type repressor HpxU in Klebsiella pneumoniae

open access: yes, 2013
Bacteria, fungi, and plants have metabolic pathways for the utilization of nitrogen present in purine bases. In Klebsiella pneumoniae, the genes responsible for the assimilation of purine ring nitrogen are distributed in three separated clusters.
