Abstract
A model is developed for hemoglobin which depends on six Bohr groups per tetramer of hemoglobin. These six groups are assumed to be located in six regions between the four subunits of hemoglobin. When the Bohr groups are assumed to be perturbed in an asymmetrical manner on binding oxygen, these groups then generate the cooperative interactions of hemoglobin. This approach makes it possible to explain oxygen binding, the Bohr effect, specific salt effects, and aggregation effects in a unified manner.
摘要
开发了一种针对血红蛋白的模型，该模型取决于每个血红蛋白四聚体的六个玻尔基团。假定这六个基团位于血红蛋白四个亚基之间的六个区域。当假定玻尔基团在结合氧气时以不对称方式受到扰动时，这些基团便会产生血红蛋白的协同相互作用。这种方法能够以统一的方式解释氧气结合、玻尔效应、特定盐效应和聚集效应。
