SUMMARY: The aspartase (l-aspartate ammonia-lyase, EC. 4.3.1.1) structural gene, aspA, was mapped by two-factor and three-factor transductional crosses using phage P1. Cotransduction frequencies between aspA and other markers were: ampA (69%); frdA (48 to 67%); mel (35%); purA (17%); fdp (1·6%). The sequence of markers within the corresponding segment (91 to 95 min) of the Escherichia coli linkage map was shown to be mel-aspA-ampA-frdA-purA-fdp.
