title: Valine-resistant Escherichia coli K-12 strains with mutations in the ilvB operon.
abstract: Escherichia coli K-12 mutants resistant to growth inhibition by valine were isolated. These strains contained mutations in the ilvB operon effecting either the regulation of acetohydroxy acid synthase I or the sensitivity of the enzyme to end product inhibition by valine.
