Localization of translocation complex components in Bacillus subtilis: enrichment of the signal recognition particle receptor at early sporulation septa.
We here demonstrate that in Bacillus subtilis, the signal recognition particle receptor, FtsY, transiently localizes to early sporulation septa, whereas three SecYEG translocase-associated membrane proteins (SecDF, SpoIIIJ, and YqjG) are uniformly distributed. These results suggest FtsY delivers secreted proteins to SecYEG at the septum, consistent with initial septal localization of forespore membrane proteins.
