Several saccharides can interact with the trimeric structure: β-D-galactose (<scene name='56/568017/Gal/1'>GAL</scene>) [http://www.ebi.ac.uk/pdbe-srv/pdbechem/chemicalCompound/show/GAL], α-D-glucose (GLC) [http://www.ebi.ac.uk/pdbe-srv/pdbechem/chemicalCompound/show/GLC] and α-D-mannose (<scene name='56/568017/Man/1'>MAN</scene>) [http://www.ebi.ac.uk/pdbe-srv/pdbechem/chemicalCompound/show/MAN].
Several saccharides can interact with the trimeric structure: β-D-galactose (<scene name='56/568017/Gal/1'>GAL</scene>) [http://www.ebi.ac.uk/pdbe-srv/pdbechem/chemicalCompound/show/GAL], α-D-glucose (GLC) [http://www.ebi.ac.uk/pdbe-srv/pdbechem/chemicalCompound/show/GLC] and α-D-mannose (<scene name='56/568017/Man/1'>MAN</scene>) [http://www.ebi.ac.uk/pdbe-srv/pdbechem/chemicalCompound/show/MAN].


These saccharides interact with the trimeric structure [http://www.ncbi.nlm.nih.gov/Structure/mmdb/mmdbsrv.cgi?uid=2z55] but also with each other and sometimes with the 2,3-Di-Phytanyl-Glycerol.
A molecule of is covalently bound to one and one ,thus creating a glucose-mannose-galactose (GLC-MAN-GAL) ligand. There is one ligand by monomer. The glucose can create a covalent bond with the molecule of 2,3-Di-Phytanyl-Glycerol.
Three α-D-glucose are bound to the Archaerhodopsin-2: one for each monomer. Each glucose forms a covalent bond with a molecule of 2,3-Di-Phytanyl-Glycerol and one with a molecule of α-D-mannose.  
 
Three α-D-mannose (one for each monomer) interact with the Archaerhodopsin-2. Each mannose forms two covalent bonds with others saccharides: one with a molecule of α-D-glucose and one with a molecule of β-D-galactose. (A VERIFIER ! 1 OU 2 / GALACTOSE ? 3 OU 6 MANNOSES ?)
