Structural plasticity in the eight-helix fold of a trematode hemoglobin
OverviewOverview
The three-dimensional structure of recombinant haemoglobin from the, trematode Paramphistomum epiclitum, displaying the highest oxygen affinity, so far observed for (non)vertebrate haemoglobins, has previously been, determined at 1.17 A resolution (orthorhombic space group P2(1)2(1)2(1))., In the present communication, the three-dimensional structure of wild-type, P. epiclitum haemoglobin is reported at 1.85 A resolution in a monoclinic, crystal form (R factor = 16.1%, R(free) = 22.0%). Comparison of P., epiclitum (recombinant versus wild-type ferric Hb) structures in the two, crystal forms shows structural differences in the haem proximal and distal, sites which have not been reported for other known haemoglobin structures, previously.
