✦ Synopsis

Two guanine nucleotide analogs, 8(6aminohexyl)-amino-guanosine-5'-triphosphate and 8(6-aminohexyl)-amino-guanosine-5'-diphosphate, were synthesized from the monophosphate by phosphorylation with pyrophosphate or orthophosphate. Structural assignments were made according to nuclear magnetic resonance spectra. The ability of these nucleotides to act as enzyme substrates has been determined. Both guanosine nucleotides were used as ligands for affinity chromatography by attaching them to Sepharose 4B by the cyanogen bromide method. The effectiveness of these new affinity columns in enzyme purification was investigated with polypeptide elongation factor II from rat and pig liver.
