Abstract

Membrane-bound respiratory [NiFe] hydrogenase is an H 2-uptake enzyme found in the periplasmic space of bacteria that plays a crucial role in energy-conservation processes. The heterodimeric unit of the enzyme from Hydrogeno-vibrio marinus was purified to homogeneity using chromatographic procedures. Crystals were grown using the sitting-drop vapour-diffusion method at room temperature. Preliminary crystallographic analysis revealed that the crystals belonged to space group P2 1, with unit-cell parameters a = 75.72, b = 116.59, c = 113.40 Å, β = 91.3°, indicating that two heterodimers were present in the asymmetric unit.
