FIG. 7.

Proposed model of Mep45 in the outer membrane. Shown are PRED-TMBB program predictions of transmembrane strands and the topology of Mep45. Transmembrane strands are shaded. The amino acid sequence with predicted high propensity to form an α-helical coiled-coil structure is underlined. Aromatic residues located near the ends of the transmembrane strand contacting the membrane surfaces are boxed. Proteinase K- and trypsin-sensitive cleavage sites are indicated as open and closed triangles, respectively.
