The tetrameric manganese superoxide dismutase from the extreme thermophile Thermus thermophilus HB8 crystallizes in space group P41212 (or its enantiomorph) with a = b = 147.5 A, c = 55.9 A. The diffraction patterns extent to 1.4 A, and the crystals are very resistant to decay induced by x-irradiation. Measurements of the crystal density in Ficoll gradients are consistent with an asymmetric unit containing the entire tetramer (Mr = 80,000).
