HUMAN DEOXYHAEMOGLOBIN-2,3-DIPHOSPHOGLYCERATE COMPLEX
Overview
The haemoglobin-2,3-diphosphoglycerate complex structure has been solved at 2.5 A resolution using crystals grown from low-salt solutions. The results show some important differences with the precedent haemoglobin-2,3-diphosphoglycerate high-salt structure solved by Arnone. First, we observe a loss of symmetry in the binding site, secondly both of the lysine residues 82 beta interact with 2,3-diphosphoglycerate at the same time, each making two contacts. This level of interaction is in agreement with the functional behaviour of natural haemoglobin mutants with mutations at the 2,3-diphosphoglycerate binding site.
