title: Polyprenyl p-hydroxybenzoate carboxylase in flagellation of Salmonella typhimurium.
abstract: Flagellation of Salmonella typhimurium was found to require a functional pathway for ubiquinone biosynthesis as well as growth in the presence of appropriate carboxylic acids. Induction of flagellation by carboxylic acids was shown to induce incorporation of p-hydroxybenzoic acid into polyprenylphenol. Constitutive flagellation was found to correlate with constitutive incorporation of p-hydroxybenzoic acid into polyprenylphenol. A novel pathway for polyprenyl p-hydroxybenzoic acid decarboxylation to polyprenylphenol was implicated in flagellation of S. typhimurium.
