ABC Maltose Transporter/Model





3D Model of the ABC Maltose Transport Channel

for further details, see Ehrmann, M., Ehrle, R., Hofmann, E., Boos, W., and A. Schlosser 1998. The ABC maltose transporter. Mol. Microbiol. 29:685-694

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.
