Diffraction data have been collected from a crystal of Thermotoga maritima mannitol dehydrogenase at the Canadian Light Source. The crystal diffracted to 3.3 A resolution and belongs to space group P2(1)2(1)2(1), with unit-cell parameters a = 83.43, b = 120.61, c = 145.76 A. The structure is likely to be solved by molecular replacement.
