The effect of hydrogen ion, chloride, and 2,3-diphosphoglycerate upon the oxygen binding of hemoglobin may be satisfactorily described by an allosteric model employing three affinity states. The allosteric two-state model does not provide even an approximate description except under defined extreme conditions. In particular, the two-state model cannot provide a correct interpretation of recently reported electron spin resonance and nuclear magnetic resonance data.
氢离子、氯离子和2,3-二磷酸甘油酸对血红蛋白氧结合的影响,可以用一个采用三种亲和力状态的别构模型令人满意地描述。除了在特定的极端条件下,别构二态模型甚至都不能提供一个近似的描述。特别是,二态模型无法对最近报道的电子自旋共振和核磁共振数据作出正确的解释。
