Determination of total potentially available nucleosides in bovine milk [PDF]

open access: yes, 2010
Bovine colostrum and milk samples were collected from two herds over the course of the first month post-partum, pooled for each herd by stage of lactation and total potentially available nucleosides were determined.

Brucella spp. Omp25 Promotes Proteasome-Mediated cGAS Degradation to Attenuate IFN-β Production

open access: yesFrontiers in Microbiology, 2021
Type I interferons (IFN), a family of cytokines widely expressed in various tissues, play important roles in anti-infection immunity. Nevertheless, it is not known whether Brucella spp.

Spontaneous assembly of an organic-inorganic nucleic acid Z-DNA double-helix structure [PDF]

open access: yes, 2017
Herein, we report a hybrid polyoxometalate organic–inorganic compound, Na2[(HGMP)2Mo5O15]⋅7 H2O (1; where GMP=guanosine monophosphate), which spontaneously assembles into a structure with dimensions that are strikingly similar to those of the naturally ...

Nonenzymatic Formation of Guanosine 3′ : 5′-Monophosphate from Guanosine Triphosphate

open access: yesJournal of Biological Chemistry, 1974
Abstract We observed the nonenzymatic formation of guanosine 3' : 5'-monophosphate (cyclic GMP) from GTP. The reaction was dependent upon heat and was accelerated by divalent cations and creatine phosphate. The formation of cyclic GMP was greater with increased incubation time, temperature, GTP concentration, and pH. All of the divalent cations tested (

The Guanylate Cyclase C-cGMP Signaling Axis Opposes Intestinal Epithelial Injury and Neoplasia. [PDF]

open access: yes, 2018
Guanylate cyclase C (GUCY2C) is a transmembrane receptor expressed on the luminal aspect of the intestinal epithelium. Its ligands include bacterial heat-stable enterotoxins responsible for traveler\u27s diarrhea, the endogenous peptide hormones ...

The T2238C human atrial natriuretic peptide molecular variant and the risk of cardiovascular diseases [PDF]

open access: yes, 2018
Atrial natriuretic peptide (ANP) is a cardiac hormone which plays important functions to maintain cardio-renal homeostasis. The peptide structure is highly conserved among species. However, a few gene variants are known to fall within the human ANP gene.

18O-Labeling of guanosine monophosphate upon hydrolysis of cyclic guanosine 3‘:5‘-monophosphate by phosphodiesterase.

open access: yesJournal of Biological Chemistry, 1980
The hydrolysis of cGMP by phosphodiesterase was conducted in [18O]water to determine the site of bond cleavage and the stoichiometry of 18O incorporation into 5'-GMP. Three different forms of phosphodiesterase including a calmodulin-calcium-dependent enzyme in its basal and activated states were examined. The hydrolysis of cGMP catalyzed by each of the
