Figure 1. ArnT topological model.

Figure 1

The model was derived using PolyPhobius and displayed with TMRPres2D. The ArnT C-terminus is oriented towards the periplasm and the protein has 13 predicted transmembrane helices, indicated by rectangles. The residues replaced by cysteine are shown in gray circles. Functional residues are indicated by black circle. The endogenous cysteines of ArnT are shown in black squares.
