タイトル Genetic and biochemical analyses of Escherichia coli strains having a mutation in the structural gene (poxB) for pyruvate oxidase.
ジャーナル J Bacteriol
Abstract Mutants of Escherichia coli K-12 deficient in pyruvate oxidase were isolated from an aceEF (pyruvate dehydrogenase-deficient) strain by selection for a complete absence of growth on medium lacking acetate. Extracts of two of the mutants were shown to contain normal levels of pyruvate oxidase antigen, although the enzymatic activities of the extracts were reduced or absent. The poxB locus was mapped by using closely linked transposon insertions to min 18.7 of the E. coli linkage map between the cmlA and aroA loci, a location far removed from that of the regulatory gene, poxA.
