Crystallographic study of cytochrome c553 from Desulfovibrio vulgaris Miyazaki.
Cytochrome c553 from the sulfate-reducing bacterium, Desulfovibrio vulgaris Miyazaki, has been crystallized. The combination of microdialysis and vapor diffusion allowed successful crystallization. The crystals were of good quality, and useful data were obtained that extended to the nominal resolution of 1.3 A. The space group is P4(3)2(1)2 with cell dimensions of a = b = 42.7 A, c = 103.4 A. More than twenty heavy-atom reagents were screened with the isomorphous replacement technique, and only the mersalyl derivative could be used for the phase determination. The single isomorphous replacement method combined with the anomalous scattering effect of the Hg-atom in mersalyl and the Fe-atom of the heme group was used for the phase determination.
