Abstract

Iron limitation and the expression of mycobactin and carboxymycobactin by Mycobacterium tuberculosis are known. Here, we report how iron regulated the coordinate expression of these two siderophores and a 28-kDa cell wall-associated iron-regulated protein (Irep-28). Irep-28 is identified as the DNA-binding HU homologue HupB protein (hupB [Rv2986c]). Antibodies to this protein were detected in sera from tuberculosis patients. The location of the protein in the cell wall makes it a potential drug target.
