TatAc, the Third TatA Subunit of Bacillus subtilis , Can Form Active Twin-Arginine Translocases with the TatCd and TatCy Subunits

This is the authors' abstract. We don't add key points for this paper.

Two independent twin-arginine translocases (Tat) for protein secretion were previously identified in the Gram-positive bacterium Bacillus subtilis. These consist of the TatAd-TatCd and TatAy-TatCy subunits. The function of a third TatA subunit named TatAc was unknown. Here, we show that TatAc can form active protein translocases with TatCd and TatCy.
