The effects of salt concentration and temperature on the thermodynamics of DNA minor groove binding have quite different signatures: binding enthalpy is salt concentration independent but temperature dependent. Conversely, binding free energy is salt dependent but essentially temperature independent through enthalpy-entropy compensation.
盐浓度和温度对 DNA 小沟结合热力学的影响具有截然不同的特征:结合焓与盐浓度无关,但与温度有关。相反,结合自由能与盐有关,但通过焓熵补偿基本上与温度无关。
