title: Crystallization and preliminary X-ray analysis of the uracil-DNA glycosylase DNA repair enzyme from herpes simplex virus type 1.
abstract: A 28.5 kDa catalytic fragment of the uracil-DNA glycosylase DNA repair enzyme from Herpes simplex virus type 1 (HSV-1) has been crystallized using protein from a highly expressing Escherichia coli clone of the Herpes simplex virus type 1 UL2 gene. The protein crystallizes at 12 mg/ml from 11% (w/v) polyethylene glycol 8000 at pH values in the range 6.8 to 7.0, in the presence of (NH4)2SO4. Long trigonal rods (0.08 mm x 0.08 mm x > 0.5 mm) diffract beyond 3.0 A using a laboratory source. The enzyme crystallizes in P3(1) (or P3(2)) a = 65.3 A, c = 49.0 A with a single molecule in the asymmetric unit and an estimated solvent content of 41% by volume.
