The role of chloride ions in modulating polyanion-induced conformational changes in haemoglobin from the dromedary (Camelus dromedarius) has been investigated. The results obtained have shown that: in the ferric derivative at pH 6.5 the effect of single polyanion (dextran sulphate and inositol hexakisphosphate) on the conformation is essentially local, thus involving only the tertiary structure of the protein; the presence of chloride ions at a concentration close to the physiological value (i.e. 150 mM) is essential to induce quaternary conformational changes in the polyanion-ferric protein system; comparison between structural and functional data correlates polyanion-induced tertiary conformational changes with changes in the value of midpoint potential, E'0, and quaternary changes with co-operativity.
