Impact of C-Terminal Chemistry on Self-Assembled Morphology of Guanosine Containing Nucleopeptides

open access: yesMolecules, 2020
Herein, we report the design and characterization of guanosine-containing self-assembling nucleopeptides that form nanosheets and nanofibers. Through spectroscopy and microscopy analysis, we propose that the peptide component of the nucleopeptide drives ...

Smartphone-Based Chemiluminescence Glucose Biosensor Employing a Peroxidase-Mimicking, Guanosine-Based Self-Assembled Hydrogel

open access: yesBiosensors, 2023
Chemiluminescence is widely used for hydrogen peroxide detection, mainly exploiting the highly sensitive peroxidase-luminol-H2O2 system. Hydrogen peroxide plays an important role in several physiological and pathological processes and is produced by ...

Antiparkinsonian Efficacy of Guanosine in Rodent Models of Movement Disorder

open access: yesFrontiers in Pharmacology, 2017
Guanosine (GUO) is a guanine-based purine nucleoside with important trophic functions and promising neuroprotective properties. Although the neuroprotective effects of GUO have been corroborated in cellular models of Parkinson’s disease (PD), its ...

Role of Guanosine Kinase in the Utilization of Guanosine for Nucleotide Synthesis in Escherichia coli [PDF]

open access: yesMicrobiology, 1989
Using purine auxotrophic strains of Escherichia coli with additional genetic lesions in the pathways of interconversion and salvage of purine compounds, we demonstrated the in vivo function of guanosine kinase and inosine kinase. Mutants with increased ability to utilize guanosine were isolated by plating cells on medium with guanosine as the sole ...

Neuromodulatory Effects of Guanine-Based Purines in Health and Disease

open access: yesFrontiers in Cellular Neuroscience, 2018
The function of guanine-based purines (GBPs) is mostly attributed to the intracellular modulation of heteromeric and monomeric G proteins. However, extracellular effects of guanine derivatives have also been recognized.

Phosphorylation of purine and pyrimidine nucleosides by isolated rat liver mitochondria [PDF]

open access: yes, 1975
Formation of 5'-AMP, 5'-GMP, 5'-CMP and 5'UMP was confirmed in isolated rat liver mitochondria incubated with alpha-ketoglutarate, inorganic phosphate, purine nucleoside and pyrimidine nucleoside. Increased incorporation of 32Pi into ATP, GTP and UTP was

In Silico and In Vitro Screening of Antipathogenic Properties of Melianthus comosus (Vahl) against Pseudomonas aeruginosa

open access: yesAntibiotics, 2021
Bacterial quorum sensing (QS) system regulates pathogenesis, virulence, and biofilm formation, and together they contribute to nosocomial infections. Opportunistic pathogens, such as Pseudomonas aeruginosa, rely on QS for regulating virulence factors ...

Guanosine Protects Neuronal PC12 Cells from Serum Deprivation-induced Cell Death

open access: yesPteridines, 2012
Survival of neurons is dependent on the presence of trophic and non-trophic factors. Previous findings showed that purine nucleosides have the potential to rescue cells from hypoxia-induced cell death. Here we demonstrate that purine nucleoside guanosine

Dynamics of Microtubule Growth and Catastrophe [PDF]

open access: yes, 2007
We investigate a simple model of microtubule dynamics in which a microtubule evolves by: (i) attachment of guanosine triphosphate (GTP) to its end at rate lambda, (ii) GTP converting irreversibly to guanosine diphosphate (GDP) at rate 1, and (iii ...
