title: Crystallization and preliminary X-ray analysis of glucose dehydrogenase from Bacillus megaterium IWG3.
abstract: Glucose dehydrogenase from Bacillus megaterium IWG3 has been crystallized in the presence of NAD(+) using the hanging-drop vapour-diffusion method with PEG 2000 as the precipitant. Crystals belong to space group C2 and have unit-cell parameters a = 120.8 (1), b = 66.7 (1), c = 119.6 (1) A, beta = 93.25 (3) degrees with standard deviations in parentheses. Assumption of four subunits in the asymmetric unit gave the most probable Matthews coefficient V(M) of 2.1 A(3) Da(-1) (solvent content 41.7% by volume). X-ray diffraction data were collected to 1.7 A on a synchrotron-radiation source.
