Production, crystallization and preliminary crystallographic analysis of Allochromatium vinosum thiosulfate dehydrogenase TsdA, an unusual acidophilic c-type cytochrome

The thiosulfate dehydrogenase TsdA from A. vinosum was recombinantly expressed, purified and crystallized. The crystals belonged to space group C2, with unit-cell parameters a = 79.2, b = 69.9, c = 57.9 Å, β = 129.3°, and diffracted to a resolution of 1.98 Å.
