Abstract
  1. A non-enzymic method for the preparation of adenosine 5'-diphosphate is described, in which the terminal phosphate of adenosine 5'-triphosphate is transferred to methanol in the presence of hydrochloric acid. The final purified product can be obtained in 60% yield. 2. Experiments with [(14)C]methanol showed that no methylation of the adenosine diphosphate occurs during the reaction. 3. Confirmation that the pyrophosphate moiety of the adenosine diphosphate produced was in the 5'-position was obtained by: (a) periodate oxidation; (b) treatment with apyrase and examination of the resulting adenylic acid isomer by paper chromatography. 4. The method appears to be generally applicable to the preparation of nucleoside 5'-diphosphates from the corresponding nucleoside 5'-triphosphates.
摘要
  1. 描述了一种制备5'-二磷酸腺苷的非酶法,其中在盐酸存在下,5'-三磷酸腺苷的末端磷酸基团转移至甲醇。最终纯化产物的产率可达60%。2. 用[(14)C]甲醇进行的实验表明,反应过程中未发生二磷酸腺苷的甲基化。3. 通过以下方法证实了所生成的二磷酸腺苷的焦磷酸部分位于5'-位:(a) 高碘酸盐氧化;(b) 用腺苷三磷酸双磷酸酶处理,并通过纸色谱法检查所得的腺苷酸异构体。4. 该方法似乎普遍适用于从相应的5'-三磷酸核苷制备5'-二磷酸核苷。
