The uptake of 4-hydroxybenzoic acid (4-HBA) in intact cells of a mutant of Klebsiella pneumoniae was investigated. Uptake of 4-HBA was shown to be an inducible system. This uptake system, at pH 7.0, has a high affinity for its substrate (apparent Kt = 13 microM) and a maximal velocity of 27.6 nmol min-1 mg protein-1. Competition studies with various structural analogs indicated a very narrow specificity of the 4-HBA uptake system. The transport system has been inhibited by inhibitors of energy… CONTINUE READING
