Abstract

A 2.9 kb DNA fragment encoding s-(2-aminoethyl)-l-cysteine (AEC) resistant aspartokinase of Corynebacteriumglutamicum was cloned on the C.glutamicum/E.coli shuttle vector pECCG117. A recombinant plasmid, designated pAK12, conferred the AEC resistance, the ability to excrete lysine and threonine, and the 3-5 fold increased specific activity of aspartokinase to host strain.
