Details | A COMPLEX OF TWO HOMEODOMAINS (THE PROTEIN COMPONENT) BOUND TO ONE 14 BASE PAIR DNA DUPLEX IS THE MOLECULAR SPECIES ANALYZED IN THIS STUDY. EACH OF THE DNA DUPLEX AND THE COMPLEX HAS PSEUDO TWO-FOLD SYMMETRY ABOUT ITS CENTER. THE ASYMMETRIC UNIT CONTAINS 1.5 COMPLEXES, ONE OF WHICH IS COMPLETELY CONTAINED WITHIN THE ASYMMETRIC UNIT AND THE OTHER OF IS BISECTED AT ITS CENTER OF SYMMETRY BY A CRYSTALLOGRAPHIC TWO-FOLD AXIS. THE TWO-FOLD AVERAGED COMPLEX WAS MODELED AS A COMPLETE SINGLE HOMEODOMAIN AND A COMPLETE SINGLE STRAND OF THE DUPLEX. THEREFORE, THE MODEL CONTAINS THREE HOMEODOMAINS AND THREE DNA STRANDS. |
