efficient protein targeting requires heterodimerization and activation of the GTPases present in the SRP receptor FtsY and the SRP protein Ffh. FtsY also forms a homodimer at the membrane using the same interaction surface as the heterodimer. Homodimerization adds to the complex interaction landscape of protein targeting. Biochemical analysis and integrative modeling suggest that the homodimer employs the same interface as the heterodimer. Ffh does not homodimerize while FtsY is able to form a homodimer. FtsY homodimer and FtsY/Ffh heterodimer share a similar interface |
