Crystallization and preliminary X-ray analysis of sulfite dehydrogenase from Starkeya novella

Crystals of purified heterodimeric sulfite dehydrogenase from Starkeya novella have been grown using vapour diffusion. X-ray diffraction data have been collected from crystals of the native protein at λ = 1.0 Å and close to the iron absorption edge at λ = 1.737 Å. The crystals belong to space group P2₁2₁2, with unit-cell parameters a = 97.5, b = 92.5, c = 55.9 Å. Native data have been recorded to 1.8 Å resolution and Fe-edge data to 2.5 Å.
