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 P 4 1 2 1 2 or P 4 3 2 1 2. The unit‐cell parameters were a = b = 76.18, c = 238.70 Å, α = β = γ = 90°.
