FIGURE 7.
Topology of AmAcr3. The topological model of AmAcr3 is based on the SCAM data from Fig. 4. The numbered residues were altered to cysteines. ●, BM-inaccessible residues; ♢, BM-accessible, AMS-inaccessible residues; ♦, residues accessible to both BM and AMS. The conserved Cys138 is located in TM4.
