The X-ray structure of S. aureus EI (SaEI) has been recently solved but structures of other bacterias have been reported before, for instance E. coli EI structure (EcEI). Although SaEI and EcEI X-ray structures are nearly the same, some differences have been observed. | The X-ray structure of S. aureus EI (SaEI) has been recently solved but structures of other bacterias have been reported before, for instance E. coli EI structure (EcEI).

Knowing the structure of S. aureus EI allows a better comprehension of the PTS mechanism. But progresses could be still done such as the possible phenomena which induce the motions of the different domains. | Knowing the structure of S. aureus EI allows a better comprehension of the PTS mechanism.
