2 poly(u) . 1 adenosine complex formation was studied by spin-technique in the temperature range from 7 to 25 degrees C. It is shown that adenosine binding induces the conformational transition of poly(u) structure from flexible coil into rigid helix. The contribution of hydrogen bonding and stacking of adenosine to the total change of enthalpy and entropy upon complex formation was estimated.
采用自旋技术在7至25摄氏度的温度范围内研究了2聚尿苷.1腺苷复合物的形成。结果表明,腺苷结合诱导聚尿苷结构从柔性卷曲构象转变为刚性螺旋构象。估算了腺苷的氢键作用和堆积作用对复合物形成时焓变和熵变总量的贡献。
