The [http://www.nature.com/nature/journal/v455/n7215/full/nature07335.html SecA] ATPase '''SecA''' drives the post-translational translocation of proteins through the SecY channel in the bacterial inner membrane. SecA is a dimer that can dissociate into monomers under certain conditions. Many bacterial proteins are transported post-translationally across the inner membrane by the Sec machinery, which consists of two essential components (1-4).
