Ferredoxin from a thermoacidophilic archaebacterium, Sulfolobus acidocaldarius, has been crystallized. The space group is P4(3)2(1)2 or P4(1)2(1)2 and the cell dimensions are a = b = 50.12 A and c = 69.52 A. The Vm value is calculated to be 1.88 A3/Da, assuming one molecule per asymmetric unit. The crystal diffracts X-rays beyond 2.0 A resolution.
