abstract

  • X-ray quality crystals of Rab guanine nucleotide dissociation inhibitor (RabGDI) from bovine brain expressed in Escherichia coli have been obtained from 1.73 M ammonium sulfate. The crystals are prismatic long rods and belong to the monoclinic space group P21 with approximate cell dimensions a = 91.9 A, b = 43.5 A, c = 63.2 A, beta = 104.5 degrees and one molecule per asymmetric unit. The crystals are stable in the X-ray beam and diffract to at least 2.3 A. Reverse screening, streak seeding and macroseeding methods were used to obtain and improve the crystals.
