Guanosine kinase from Trichomonas vaginalis
Molecular and Biochemical Parasitology, 1991A novel guanosine kinase was partially purified from the parasitic protozoan Trichomonas vaginalis. Unlike nucleoside kinases from other sources, the preferred substrate for this enzyme was guanosine (Vmax/Km = 120). The enzyme also catalyzed the phosphorylation of inosine (Vmax/Km = 3), uridine (2), adenosine (0.5), cytidine (0.2), and 2 ...

Abstract The nucleotide sequence of the GDPase gene (GenBank accession# L79560) reveals a 1554 bp open reading frame encoding a polypeptide of 518 amino acids4. Three potential N-glycosylation sites are present in the sequence. Hydropathy plots suggest that it is a type II membrane proteins with a hydrophobic stretch of 16 amino acids ...

CONDENSATION OF TRIFORMYLMETHANE WITH GUANOSINE
Nucleosides, Nucleotides and Nucleic Acids, 2001Guanosine has been reacted with triformylmethane (TFM) in refluxing pyridine. Four different products, 4-7, were isolated by preparative RP-HPLC, and characterized by 1H and 13C NMR and UV spectroscopy and mass spectrometry. One of the products. the cyclic 1:1 adduct 4, is a stable cyclic carbinolamine formed probably by cyclization of the expected ...

Oxidation potentials of guanine, guanosine and guanosine-5′-monophosphate: Theory and experiment
Electrochimica Acta, 2019Abstract Guanine, having lower one-electron oxidation potential than other nucleobases, is of relevance to oxidative degradation of nucleic acids in mutagenesis, carcinogenesis, and aging. Here we compare oxidation potentials of guanine (G), guanosine (Guo), deoxyguanosine (dGuo), guanosine -5′- monophosphate (GMP) and 2′- deoxyguanosine -5 ...

Reactions of formaldehyde with guanosine
Toxicology Letters, 1981Formaldehyde reacted with guanosine and the products were assayed using fluorescence spectroscopy at different pHs. The reaction products were fluorescent in alkali only as was found with commercial N-2 methylguanosine. Thus, formaldehyde appeared to react with N-2 of guanosine. The reaction was completed with 30s both at 0 degrees C or at 21 degrees C.
