Crystallization and Preliminary X-ray Studies of <E5>l</E5>-Aspartase from Escherichia coli

Single crystals of <E5>l</E5>-aspartate ammonia-lyase (<E5>l</E5>-aspartase) from Escherichia coli have been obtained by microdialysis at room temperature using polyethylene glycol 3350 and sodium acetate as co-precipitants. The crystals exhibit the symmetry of space group P2₁2₁2 with a = 156·5 Å, b = 147·6 Å, c = 102·5 Å and diffract at least to 2·8 Å. Copyright 1993, 1999 Academic Press
