CRYSTALLIZATION AND PRELIMINARY CRYSTALLOGRAPHIC INVESTIGATION OF ELECTRON-TRANSFER FLAVOPROTEIN FROM THE BACTERIUM METHYLOPHILUS W3A1

Electron-transfer flavoprotein from Methylophilus W3A1 has been crystallized using the sitting drop vapour diffusion technique. Hexagonal crystals, suitable for high-resolution structure determination grow to approximately 0.7 mm × 0.7 mm × 0.5 mm in size and diffract to at least 2.2 Å. The space group is either P61 or P65 with unit cell dimensions a, b = 119.1 Å and c = 85.6 Å. © 1994 Academic Press Limited.
