The preprotein translocase YidC controls respiratory metabolism in Mycobacterium tuberculosis.

ABSTRACT: The YidC-Oxa1-Alb3 preprotein translocases play a vital role in membrane insertion of proteins in eukaryotes and bacteria. In a recent study we observed that Rv3921c, which encodes putative YidC translocase in Mycobacterium tuberculosis (Mtb), is essential for in vitro growth of bacteria. However, the exact function of this particular protein remains to identify in mycobacterial pathogens. By performing a systematic study here we show that YidC of Mtb is an envelope protein, which is required for production of ATP and maintenance of cellular redox balance. Drastic effects of depletion of Rv3921c on the expression of hypoxic genes, ATP synthases, and many proteins of central metabolic and respiratory pathways shed a significant light on the function of YidC towards controlling respiratory m
