Abstract
Crystals of oxidized Desulfovibrio vulgaris flavodoxin have been studied by X-ray diffraction techniques. The structure has been determined at 2.5 A resolution. The molecule consists of a pleated sheet core with two sections of helix on each side of the sheet. The FMN group is distinguishable: it is mostly burried but 7- and 8-Methyl groups appear to be at the surface of the protein.
