Mutants resistance to various combinations of threonine, lysine and/or their analogs were obtained and characterized in Pseudomonas acidovorans. In particular, mutants resistant to aminoethylcysteine had a dihydrodipicolinate synthetase insensitive to lysine inhibition whereas mutants resistant to threonine plus a low concentration of aminoethylcysteine had a feedback-insensitive aspartokinase.
