A periplasmic cinched protein is required for siderophore secretion and virulence of Mycobacterium tuberculosis

Abstract

The pathogen Mycobacterium tuberculosis uses the siderophores called mycobactins and carboxymycobactins to acquire iron from the host. Here, Zhang et al. identify a protein that is important for siderophore secretion and for the pathogen’s growth in low-iron medium.
