Abstract
Glyceraldehyde-3-phosphate dehydrogenase from Antheraea mylitta (AmGAPDH) was cloned in pQE30 vector, overexpressed in Escherichia coli M15 (pREP4) cells and purified to homogeneity. The protein was crystallized using the hanging-drop vapour-diffusion method. The crystals belonged to the orthorhombic space group I222, with unit-cell parameters a = 85.81, b = 133.72, c = 220.37 A. X-ray diffraction data were collected and processed to a maximum resolution of 2.2 A. The presence of three molecules in the asymmetric unit gave a Matthews coefficient (V(M)) of 2.80 A(3) Da(-1), with a solvent content of 56.08%.
