Abstract

ABSTRACT The SufBCD complex is an essential component of the SUF machinery of [Fe-S] cluster biogenesis in many organisms. We show here that in Mycobacterium tuberculosis the formation of this complex is dependent on the protein splicing of SufB, suggesting that this process is a potential new target for antituberculous drugs.
