Crystallization and preliminary X‐ray analysis of L‐serine 3‐dehydrogenase complexed with NADP + from the hyperthermophilic archaeon Pyrobaculum calidifontis

An NAD(P) + ‐dependent L‐serine 3‐dehydrogenase from the hyperthermophilic archaeon Pyrobaculum calidifontis was crystallized using the sitting‐drop vapour‐diffusion method with ammonium sulfate as the precipitant. The crystals belonged to the monoclinic space group C 2, with unit‐cell parameters a = 120.81, b = 57.40, c = 56.37 Å, β = 106.88°. Diffraction data were collected to 1.57 Å resolution on beamline NE3A at the Photon Factory. The overall R merge was 4.2% and the data completeness was 90.1%.
