What's a GeneRIF?
  1. This study analyzed in detail the H+ pathway in the perspective to update the chemiosmotic theory. The study is based on structural computer simulations on the subunit a/c complex of E. coli. This study allowed to identify a plausible H+ pathway taking into consideration the hydrogen-bonded chain mechanism, thereby excluding the contribution of water molecules.
