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 x 0.7 mm x 0.5 mm in size and diffract to at least 2.2 A. The space group is either P6(1) or P6(5) with unit cell dimensions a,b = 119.1 A and c = 85.6 A.
