Figure 4

Transmembrane region of succinate dehydrogenase (PDB: 1NEK): top view of the helical bundle (center) and side views of the lipid accessible helices. Predicted residues on the lipid accessible faces are shown in CPK color, the rest of the molecule is in orange. Labels for helices from the SdhC subunit are in red, and labels for helices from the SdhD subunit are in blue. Predicted lipid-facing residues from the tm II helices of SdhC and SdhD are shown on two separate side views, because these helices traverse the helical bundle and appear on two different sides of the TM domain.
