Crystallographic data for cytochrome c3 from two strains of Desulfovibrio vulgaris, Miyazaki.

Two crystalline forms of cytochrome c3 isolated from two strains of Desulfovibrio vulgaris, Miyazaki, tentatively designated as D. vulgaris, Miyazki F and D. vulgaris, Miyazaki K, have been found. Both belong to the orthorhombic system, space group P2(1)2(1)2(1), but have different cell dimensions; a=54.1, b=68.9 and c=35.0 A for D. vulgaris, Miyazaki F, and a=43.5, b=41.2, and c=62.9 A for D. vulgaris, Miyazaki K. The asymmetric unit of each crystal contains one molecule of cytochrome c3.
