Notes:
Crystals of Escherichia coli asparagine synthetase have been obtained from 45% saturated ammonium sulfate solution at pH 7.5 by using its Cys-free (Cys51→Ala, Cys315→Ala) mutant. The crystals belong to space group P21, with cell dimensions a = 52.90(4), b = 126.2 (2), c = 52.8 (1) Å and β = 105.3(1)°. The self-rotation function specifies that there is one dimer in the asymmetric unit and the subunits are related by a non-crystallographic twofold axis. Complete data sets up to 2.7 Å resolution have been collected on an R-AXIS IIc imaging-plate system.
