Brefeldin A-ADP ribosylated substrate (BARS) is a newly discovered enzyme involved in membrane fission, catalyzing the formation of phosphatidic acid by transfer of an acyl group from acyl-CoA to lysophosphatidic acid. A truncated form of BARS, lacking the C-terminal segment expected to interact with the Golgi membrane, has been expressed in soluble form in Escherichia coli, purified and crystallized. BARS crystals diffract up to 2.5 A resolution using synchrotron radiation and belong to space group P6(2)22/P6(4)22, with unit-cell parameters a = b = 89.2, c = 162.6 A, alpha = beta = 90, gamma = 120 degrees and one molecule (39.5 kDa) per asymmetric unit. SeMet-substituted BARS has been crystallized under growth conditions very similar to those of the native protein.
