詳細 | THE ENTIRE PROTEIN IS A TETRAMER, BUT THE ASYMMETRIC UNIT CONTAINS A DIMER. THE TWO DIMERS ARE RELATED BY A TWO FODL AXIS, WHILST THE TWO INDEPENDENT MONOMERS IN THE DIMER ARE RELATED BY A PSEUDO TWO-FOLD AXIS. THE LIGAND IS BOUND IN THE INTERNAL CHANNEL, MADE UP BY THE TWO INDEPENDENT MONOMERS. A CRYSTALLOGRAPHIC TWO-FOLD AXIS RUNS THROUGH THE CHANNEL, MAKING IT SYMMETRIC. MOREOVER, PERPENDICULAR TO THE PREVIOUS ONE, THERE IS THE PSEUDO TWO-FOLD, WHICH MAKES THE TWO HALFS OF THE CHANNEL NEARLY IDENTICAL. AS A RESULT OF ALL THAT, TWO INDEPENDENT BINDING SITES ARE PRESENT PER TERAMER, BUT, SINCE THE LIGAND IN THIS CASE DOES NOT PRESENT ANY SYMMETRY, EACH LIGAND IN THE CRYSTAL APPEARS TO BE SUPERIMPOSED TO ITS SYMMETRY-RELATED. IN CONCLUSION, FOUR RETINOIC ACID BOUND MOLECULES ARE SEEN, EACH PAIRS SUPERIMPOSED. IN ADDITION, SOLUTION DATA STRONGLY SUGGEST THAT ONLY ONE LIGAND MOLECULE IS BOUND TO A TTR TETRAMER. IN CONCLUSION, THE COORDINATES OF TWO 9CR MOLECULES ARE GIVEN, WHICH APPLYING THE CRYSTALLOGRAPHIC SYMMETRY, BECOMES FOUR, BUT ONLY ONE MUST BE CONSIDERED STATISTICALLY PRESENT IN THE TETRAMER. |

THE OCCUPANCIES OF SITES WERE NOT REFINED, SINCE THE ELECTRON DENSITY REFLECTS THE PRESENCE OF THE CRYSTALLOGRAPHIC TWO-FOLD AXIS. IN THE FUNCTIONAL TETRAMER THE RETINOIC ACID MOLECULES ARE DISORDERED DUE TO THE CRYSTALLOGRAPHIC TWO-FOLD RUNNING THROUGH THE BINDING SITE. RESIDUES 1 - 9 OF BOTH CHAINS, AS WELL AS 126 - 127 OF CHAIN B, ARE ILL-DEFINED IN THE ELECTRON DENSITY. THEY HAVE BEEN INCLUDED, BUT THE TEMPERATURE FACTORS ARE VERY HIGH.
