Abstract

Crystals of the high-potential iron-sulfur protein from Ectothiorhodospira halophila strain BN 9626 have been grown from 3.4 to 3.5 M ammonium sulfate solutions at pH 7.5. The crystals belong to the space group P21 with unit cell dimensions of a = 60.00 A, b = 31.94 A, c = 40.27 A, and beta = 100.5 degrees. There are 2 molecules/asymmetric unit. The crystals diffract to at least 1.8 A, are stable in the x-ray beam, and are suitable for a high resolution x-ray crystallographic analysis.
