Disulfide bonds are important for the stability and function of many secreted
proteins. In Gram-negative bacteria, these linkages are catalyzed by
thiol-disulfide oxidoreductases (Dsb) in the periplasm. Protein oxidation has
been well studied in these organisms, but it has not fully been explored in
Gram-positive bacteria, which lack traditional periplasmic compartments. Recent
bioinformatics analyses have suggested that the high-GC-content bacteria (i.e.,
actinobacteria) rely on disulfide-bond-forming pathways. In support of this,
Dsb-like proteins have been identified in Mycobacterium tuberculosis, but their
functions are not known. Actinomyces oris and Corynebacterium diphtheriae have
recently emerged as models to study disulfide bond formation in actinobacteria.
In both organisms, disulfide bonds are catalyzed by the membrane-bound
oxidoreductase MdbA. Remarkably, unlike known Dsb proteins, MdbA is important for
pathogenesis and growth, which makes it a potential target for new antibacterial
drugs. This review will discuss disulfide-bond-forming pathways in bacteria, with
a special focus on Gram-positive bacteria.
