We isolated a strain (PS187) containing a mutation in the ilvA structural gene (threonine deaminase) affecting the regulation of the isoleucine and valine biosynthetic enzymes. We studied the effect of the mutation, ilvA538, on the ability of the ilv

An ilv A gene (specifying threonine deaminase) mutation causes an Escherichia coli K12 strain to be leucine sensitive. The regulation of all the isoleucine and valine biosynthetic enzymes and of the branched chain aminoacyl-tRNA synthetases is affect
