Abstract
Binding of inositol hexakisphosphate (IHP) to the oxygenated derivative of dromedary (Camelus dromedarius) and human hemoglobin (Hb) was investigated by 31P-NMR. The results obtained show that dromedary Hb binds, with different affinity, two IHP molecules per tetramer at distinct sites, while human Hb binds only one IHP molecule per tetramer.
摘要
通过31P核磁共振研究了肌醇六磷酸（IHP）与单峰驼（Camelus dromedarius）和人血红蛋白（Hb）的氧化衍生物的结合情况。所得结果表明，单峰驼血红蛋白每个四聚体在不同位点以不同亲和力结合两个IHP分子，而人血红蛋白每个四聚体仅结合一个IHP分子。
