Abstract

1. 1. Sheep aquomethaemoglobins A and B exert similar paramagnetic influence on the solventproton magnetic relaxation (PMR) rates as observed in human HbA, even in the presence of inositol hexaphosphate (IHP). 2. 2. On the other hand, phosphate-free methaemoglobin C induces smaller PMR rates due to the restricted haem-accessibility. 3. 3. Here IHP also binds, although with smaller affinity and with different structural consequences from the other two sheep haemoglobins. Some implications of these findings are discussed here.
