Summary of model pore system setup. (A) X-ray structure of the full αHL protein pdb code = 7AHL and (B) the model pore embedded in a methane slab. The protein barrel region that was incorporated into the model pore is colored yellow in A and B. Cut-away view of the molecular surface of the model pore embedded within a methane slab (C). The charged residues E111 and K147 (red and blue respectively) at the cis (near vestibule) mouth of the barrel are included in the model, whereas the trans mouth (opposite end from vestibule) is truncated at residue N123 (green).
