    Abstract:
    We have obtained two additional crystal forms of the metal-dependent class II fructose-1,6-bisphosphate aldolase from Escherichia coli. Crystals in the shape of elongated plates have unit-cell dimensions a = 73.4, b = 120.0, c = 190.1 A, orthorhombic space group P2(1)2(1)2(1). Monoclinic prisms have unit-cell dimensions a = 67.7, b = 104.3, c = 52.8 A, beta = 105 degrees, space group P2(1). Diffraction to slightly better than 3.0 A, has been observed for both forms using in-house and synchrotron facilities. These crystal forms may aid the structure solution of this enzyme by presenting additional forms for heavy-atom derivatization. These forms have multiple copies of the enzyme in the asymmetric unit and averaging methods might also be useful in the analysis.
