The structure of the class II zinc-ion dependent L-fuculose-1-phosphate, aldolase from Escherichia coli in its tetragonal crystal form has been, established at 1.92 A resolution. The homotetrameric enzyme has a, molecular mass of 4 x 24 kDa and follows C(4) symmetry. The structure, model is exactly symmetrical, which contradicts an observed birefringence, anomaly of the crystals. The four catalytic centers are located in deep, clefts at the interfaces of adjacent subunits. The zinc ion is coordinated, by three histidines and one glutamate in an almost tetrahedral, arrangement. In contrast to numerous other catalytically competent zinc, ions, there is no water molecule in the ligand sphere. Replacement of zinc, by a cobalt ion caused only small structural changes.
