Abstract excerpt
The trp repressor of Escherichia coli binds to the operators of three operons concerned with tryptophan biosynthesis and regulates their expression. trp superrepressors can repress expression of the trp operon in vivo at lower tryptophan concentrations than those required by the wild-type repress...
