a The angle between the two monomers in a dimer viewed from the longer side of the dimer along the membrane plane. There is around 12° bending between the two monomers. b The angle between the two monomers in a dimer viewed from the shorter side of the dimer along the membrane plane (black arrow). There is around 10° twisting between the two monomers.
