Identification of the ahp operon of Salmonella typhimurium as a macrophage-induced locus.

By K P Francis, P D Taylor, C J Inchley and M P Gallagher

Abstract

Previously, we tagged a macrophage-induced Salmonella typhimurium locus with Mudlux (K. P. Francis and M. P. Gallagher, Infect. Immun. 61:640-649, 1993). The insertion lies within the OxyR-regulated ahpC locus and conveys alkyl peroxide sensitivity. Plasmid-encoded ahp reverses sensitivity but reduces luminescence. This suggests that OxyR is titrated by the multicopy ahp promoter
