Crystallization and preliminary X-ray diffraction analysis of MJ0458, an adenylate kinase from Methanocaldococcus jannaschii.

Adenylate kinase plays a very important role in regulating adenylate species in the cell. Methanocaldococcus jannaschii is a rich resource of unique enzymes. Here, MJ0458, an adenylate kinase from M. jannaschii, was crystallized. A set of X-ray diffraction data to 2.70 Å resolution was collected on beamline BL-17U of the Shanghai Synchrotron Radiation Facility (SSRF). The crystal belonged to space group P4(1)2(1)2 or P4(3)2(1)2. The unit-cell parameters were a = b = 76.18, c = 238.70 Å, α = β = γ = 90°.
