The goal of my research is to enable the systematic identification of substrates of the disulfide bond formation pathways of two human pathogens, Pseudomonas aeruginosa and Mycobacterium tuberculosis as well as to characterize the pathways that introduce disulfide bonds in Clostridia and in the gut microbiome using E. coli tools. We will determine whether microorganisms in the gut microbiome modulate the virulence/growth of other microorganisms by inhibiting their disulfide bond formation pathways targeting either DsbB, VKOR or DsbA homologues and we will investigate the impact of the bacterial and archaeal disulfide bond formation pathways in the gut microbiome by in situ identification of the proteins that are secreted and disulfide bonded to the extracellular milieu.
