Antibodies to the Terminal Moieties of Guanine Mononucleotides and Guanine-Containing Dinucleotides
1968Antibodies specific for nucleic acids have been obtained by immunizing rabbits with conjugates composed of bases, nucleosides or nucleotides covalently linked to proteins or polyamino acids. The chemical methods used to prepare such immunogens have been reviewed (Levine and Stollar, 1967) and the characteristics of some of these antibodies are ...

Synthesis of monomers containing guanine or guanine precursors as substituent groups
Journal of Polymer Science Part A: Polymer Chemistry, 1991AbstractThe synthesis of four new monomers containing guanine or a guanine precursor was achieved. These were two isomeric acid ester derivatives of guanine and two isomeric vinyl ether derivatives of N2âacetylguanine. In the case of the synthesis of the guanine acid esters IV and V, it was necessary to prepare first the guanine alcohol derivatives II ...

THE MECHANISM AND SPECIFICITY OF GUANINE DEAMINASE
Canadian Journal of Biochemistry, 1967Guanine deaminase from lingcod muscle has been found to remove chlorine from 2-chloro-6-hydroxypurine, hydrazine from 2-hydrazino-6-hydroxypurine, and methylamine from 2-methylamino-6-hydroxypurine, with xanthine as the product in all cases. Methylation of guanine on nitrogen atoms other than N-1 and substitutions at C-6 eliminate susceptibility to ...

A fluorimetric assay for guanine aminohydrolase
Analytical Biochemistry, 1974Abstract A rapid, sensitive, and versatile assay for guanine aminohydrolase is described. It is based on the difference in native fluorescence of guanine, the substrate, and xanthine, the reaction product when excitation and emission wavelengths are 285 nm and 345 nm, respectively.
