title: Complementation between different mutations in the ilvA gene of Escherichia coli K-12.
abstract: An ilvA mutation carried by a ø80i(lambda)dilv transducing phage complemented some ilvA mutations and did not complement others. Complementation was accompanied by appearance of threonine deaminase activity in vivo. These results divided the ilvA mutations into two sets which formerly appeared to define two cistrons.
