Fig. 2From: Role of electrostatic interactions for ligand recognition and specificity of peptide transportersOverall structure of YePEPT. Structure of YePEPT viewed in the plane of the membrane (top) and from the cytosol (bottom). The N- and C-terminal six-helix bundles are colored in red and blue, respectively. The two helices HA and HB connecting the two bundles are colored in gold. The N- and C-termini are labeled. In the top view (bottom) the transmembrane helices H1–H12, and HA and HB are labeled. Parts of the loops connecting H6 and HA, and H8 and H9 that could not be traced are indicated by broken linesBack to article page
