A predicted topology of Deh4p. A topological model of Deh4p derived from the SOSUI prediction (bp.nuap.nagoya-u.ac.jp/sosui). The relative locations of the fusion reporters are indicated by numbers and colored residues. Qualitative dual-reporters activities are shown as red-colored circles (the LacZ activity was at least 3-fold higher than the PhoA activity), blue-colored hexagons (the PhoA activity was at least 3-fold higher than the LacZ activity), orange-colored circle (the LacZ activity was higher than the PhoA activity but less than 3-fold), and purple-colored hexagons (higher PhoA than LacZ activity but less than 3-fold). The twelve putative TMS are also indicated as numbers in circles. The conserved MFS signature motif of [RK]XGR [RK] is highlighted in yellow.
