RESIDUES 106 - 114 WERE FIRST FIT IN A NON-WILDTYPE REMARK 3 CONFORMATION. AFTER REFINEMENT THE WILDTYPE CONFORMATION WAS REMARK 3 VISIBLE IN FO-FC DIFFERENCE MAPS, AND WAS ADDED TO THE MODEL. REMARK 3 RELATIVE OCCUPANCIES WERE ESTIMATED BASED ON REFINED GROUP REMARK 3 OCCUPANCIES (INITIALLY AT 0.5) AND EITHER FIXING OR REFINING REMARK 3 THE B VALUES AND POSITIONS. THE WEIGHTS OF EACH CONFORMER ARE REMARK 3 0.6 (ALT) AND 0.4 (WT). IN MOST T4 MUTANT STRUCTURES, RESIDUES REMARK 3 163 AND 164 ARE DISORDERED AND NOT OBSERVED IN ELECTRON REMARK 3 DENSITY MAPS. IN THIS MUTANT, THESE RESIDUES WERE RESOLVED IN REMARK 3 REFINED FO-FC DIFFERENCE MAPS AND THE RESIDUES ADDED TO THE REMARK 3 MODEL.

THE MUTANT REMARK 400 WAS DESIGNED TO CREATE A DEEP PIT BY TRUNCATING MET 102 AND REMARK 400 MET 106 TO ALA. THE STRUCTURE OF SINGLE MUTANT MET102-ALA REMARK 400 HAS A BURIED NON-POLAR CAVITY THAT BINDS BENZENE, AND THE REMARK 400 MET 106 SIDE CHAIN SEPARATES THE CAVITY FROM THE SURFACE. REMARK 400 THE DOUBLE MUTANT FAILED TO BIND ANY LIGANDS DETECTABLY. REMARK 400 THE STRUCTURE DISPLAYED TWO DIFFERENT CONFORMATIONS FOR THE REMARK 400 REGION 106 - 114, WHICH IS SHORT MOBILE HELIX IN WILDTYPE. REMARK 400 THE PREDOMINANT CONFORMER CONTAINED THREE LEFT-HANDED REMARK 400 GLYCINES (107, 110, 113) WHILE THE LESSER POPULATED REMARK 400 CONFORMER WAS WILDTYPE-LIKE. THE WEIGHTS WERE 0.6 (ALT) REMARK 400 AND 0.4 (WILDTYPE). THE SWITCH IN CONFORMATION IS REMARK 400 ATTRIBUTED TO CHANGES IN PACKING OF THE HYDROPHOBIC FACE OF REMARK 400 THE HELIX.
