A membrane protein complex, succinate dehydrogenase (SQR) from Escherichia coli has been purified and crystallised. This enzyme is composed of four subunits containing FAD, three iron–sulphur clusters and one haem b as prosthetic groups. The obtained crystals belong to the hexagonal space group P63with the unit-cell dimensions of a=b=123.8 Å and c=214.6 Å. An asymmetric unit of the crystals contains one SQR monomer (Mr120 kDa). A data set is now available at 4.0 Å resolution with 88.1% completeness and 0.106 Rmerge. We have obtained a molecular replacement solution that shows sensible molecular packing, using the soluble domain of E. coli QFR (fumarate reductase) as a search model. The packing suggests that E. coli SQR is a crystallographic trimer rather than a dimer as observed for the E. coli QFR.
