我们已经确定了一种T型血红蛋白的结构,其中β亚基的血红素基团与一氧化碳结合,而α亚基的镍取代了血红素铁,并且没有配体。T态结合配体的结构调整方向与与四元跃迁相关的方向一致,血红素的平移受到严格限制。我们解释了这些观察如何解释T状态血红蛋白β血红蛋白的低配基亲和力的原因。
We have determined the structure of a T-state haemoglobin in which the haem groups of the β subunits have carbon monoxide bound, and the α subunits have nickel replacing the haem iron and are ligand-free. The structural adjustments on binding ligand in the T state are in the same direction as those associated with the quaternary transition, and a translational shift of the haem is severly restricted. We explain how these observations may account for the low ligand affinity of the β haem of T-state haemoglobin.
