Abstrak
Bar-headed goose fluoromethaemoglobin (fluoromet-Hb) complexed with inositol hexaphosphate (IHP) has been crystallized using PEG 6000 as precipitant. The crystal belongs to space group P2(1), with unit-cell parameters a = 59.8, b = 72.0, c = 79.8 A, beta = 102.1 degrees, and diffracts to 2.5 A resolution. To prove the presence of IHP, the structure was determined by the molecular-replacement method. IHP was observed at the entrance to the central cavity between the N and C termini of two beta subunits.
