Popis: | Evidence is presented here confirming the identification of guanosine 3′: 5′-monophosphate (c GMP) in the tissue of higher plants. The c GMP activity detected in fruits of Zizyphus jujuba was separated from the c AMP activity also present. The separated sample was extensively purified by Bio-Rad AG 1 × 4 and aluminium oxide CC, and by TLC. The purified sample showed the same physicochemical properties as authentic c GMP by TLC using different solvents and by UV spectroscopy, and was decomposable by cyclic nucleotide-specific phosphodiesterase. The identification was further supported by HPLC. The amount of c GMP present increases 90-fold during fruit ripening. |
