Structure of deoxy-quaternary haemoglobin with liganded beta subunits


Overview

We have determined the structure of a T-state haemoglobin in which the haem groups of the beta subunits have carbon monoxide bound, and the alpha 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 severely restricted. We explain how these observations may account for the low ligand affinity of the beta haem of T-state haemoglobin.
