    Abstract:
    The complex of bovine factor Xa and recombinant tick anticoagulant peptide (rTAP) was crystallized in two different crystal forms using polyethylene glycol as a precipitant. Form I belongs to space group P42212 with unit-cell dimensions a = b = 133.1, c = 68.8 A. It contains one complex per asymmetric unit and diffracts to 3.0 A resolution. Form II belongs to P41212 (or P43212) with dimensions a = b = 126.5, c = 146.7 A; it contains two complexes per asymmetric unit and diffracts to 2.5 A. The crystals of both forms consist of factor Xa (MW = 45.3 kDa) and rTAP (MW = 6.7 kDa).
