a Alignment of FGSG_02655 with a sequence of human glucagon G-protein coupled receptor (4L6R). This alignment was used to build the model 1. b Alignment of FGSG_02655 with sequences of human G protein-coupled metabotropic glutamate receptor 1 (4OR2) and human metabotropic glutamate receptor 5 (4OO9). This alignment was used to build the model. c Alignment of FSG_02655 with sequences of G protein-coupled metabotropic glutamate receptor 1 (4OR2), the human dopamine D3 receptor (3PBL) and human glucagon G-protein coupled receptor (4L6R). This alignment was used to build the model 3. Red squares correspond to transmembrane helix positions
