Carbachol in the presence of guanosine 5′-O-(3-thiotriphosphate) stimulates the breakdown of exogenous phosphatidylinositol 4,5-bisphosphate, phosphatidylinositol 4-phosphate, and phosphatidylinositol by rat brain membranes

Journal of Biological Chemistry, 1989
The breakdown of exogenously added [3H]inositol-labeled phosphoinositides by rat brain cortical membranes was stimulated by the muscarinic cholinergic agonist carbachol. The stimulation required the presence of guanine nucleotide. Optimal conditions were similar to those described for guanosine 5'-O-(3-thiotriphosphate) (GTP gamma S) + carbachol ...

STOMATAL OPENING IS INDUCED IN EPIDERMAL PEELS OF COMMELINA-COMMUNIS L BY GTP ANALOGS OR PERTUSSIS TOXIN [PDF]

, 1993
Pretreatment with pertussis toxin or microinjection of guanosine-5'-(3-thiotriphosphate) (GTP-gamma-S) into guard cells in peeled epidermis of Commelina communis L. promoted stomatal opening under subsaturating white light.

Advanced Binary Guanosine and Guanosine 5'‑Monophosphate Cell-Laden Hydrogels for Soft Tissue Reconstruction by 3D Bioprinting

, 2023
Soft tissue defects or pathologies frequently necessitate the use of biomaterials that provide the volume required for subsequent vascularization and tissue formation as autrografts are not always a feasible alternative.

Evidence that a beta-adrenergic receptor-associated guanine nucleotide regulatory protein conveys guanosine 5'-O-(3-thiotriphosphate)- dependent adenylate cyclase activity.

Journal of Biological Chemistry, 1981
The guanine nucleotide regulatory protein component (N) of the frog erythrocyte membrane adenylate cyclase system appears to form a stable complex with the beta-adrenergic receptor (R) in the presence of agonist (H). This agonist-promoted ternary complex HRN can be solubilized with Lubrol.

Guanosine 5'-O-(3-thiotriphosphate) as an analog of GTP in protein biosynthesis. The effects of temperature and polycations on the accuracy of initial recognition of aminoacyl-tRNA ternary complexes by ribosomes.

Journal of Biological Chemistry, 1986
Guanosine 5'-O-(3-thio)triphosphate (GTP gamma S) is a good analog of GTP in the reactions leading to the formation of a peptide bond in protein biosynthesis. It forms binary and ternary complexes with elongation factor Tu (EF-Tu), and with EF-Tu and aminoacyl-tRNA (aa-tRNA). In addition, it stimulates aa-tRNA binding to ribosomes. Although GTP gamma S

Chlorine Dioxide Oxidation of Guanosine 5‘-Monophosphate

, 2016
The reactions between aqueous ClO2 and guanosine 5‘-monophosphate (5‘-GMP) are investigated from pH 5.96 to 8.30. The decay of ClO2 follows mixed first-order and second-order kinetics.
