Purine Degradative Pathway of the Yam and Sweet Potato

, 1986
The degradation of purines by nitrogen-deficient plants was investigated in the carbohydrate staples yam tubers (Dioscorea spp.) and sweet potatoes (Ipomoea batatas).

CONSEQUENCES OF PURINE DEGRADATION INHIBITION INDUCED BY ALLOPURINOL ON GROWTH, NITROGENOUS COMPOUNDS AND CARBOHYDRATES IN YAM BEAN (Pachyrhizus erosus Urban) [PDF]

, 2017
Allopurinol effects on Xanthine dehydrogenase (XDH) and uricase, the key enzymes of conversion of fixed nitrogen in ureides (allantoin and allantoate), exporting forms of ammonia from nodules to leaves, where investigated on growth, amino-compounds and ...

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

The 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.

Gene Context Analysis Reveals Functional Divergence between Hypothetically Equivalent Enzymes of the Purine–Ureide Pathway

, 2016
A major problem of genome annotation is the assignment of a function to a large number of genes of known sequences through comparison with a relatively small number of experimentally characterized genes.

Caracterización molecular del metabolismo del alantoato en judía (Phaseolus Vulgaris) [PDF]

, 2012
En plantas, la degradación del alantoato es un paso indispensable para el reciclaje de las bases nitrogenadas. Además, en las leguminosas tropicales, como judía y soja, los ureidos alantoína y alantoato son las formas mayoritarias de transporte del ...

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

Scientifica, 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

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

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

, 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.

Phylogenetic classification of the major superfamily of membrane transport facilitators, as deduced from yeast genome sequencing. [PDF]

, 1995
From the approximately 5000 open reading frames presently identified by systematic sequencing of the yeast genome, 100 Saccharomyces cerevisiae transport proteins belonging to the major facilitator superfamily (MFS), were assigned to 17 families on the ...
