Ferredoxin (Fd) dependent glutamate synthase (Fd-GOGAT) is a key enzyme involved in nitrogen assimilation that catalyzes the two-electron reductive conversion of Gln and 2-oxoglutarate to two molecules of Glu. Fd serves as an electron donor for Fd-GOGAT and the two proteins form a transient electron-transfer complex. In this study, these two proteins were cocrystallized using the hanging-drop vapour-diffusion method. Diffraction data were collected and processed at 2.65 angstrom resolution. The crystals belonged to space group P43, with unit-cell parameters a = b = 84.95, c = 476.31 angstrom.
