Example of an asymmetric assembly with internal pseudo-symmetry in one of the chains.
(a) The ABC transporter (PDB 4FI3). (b) The BtuF periplasmic domain with internal C2 pseudo-symmetry highlighted, including the 2-fold axis of symmetry. The internal symmetry calculation was performed with CE-Symm [35].
