The pictures show the transport channel composed of the 14 transmembrane domains of the MalFG subunits.
1. MalFG+LamB.gif shows the MalFG channel (left) and the LamB-monomer channel (right). Hydrophobic residues are in black, non-hydrophobic residues in yellow colour.
Comparison of MalFG and LamB
2. all_slices.gif shows the MalFG channel sliced open at 4 different positions. Again, hydrophobic residues are in black, non-hydrophobic residues in yellow colour.
Looks into the channel
Note that there are several strongly hydrophobic regions within the channel.
