THE MODEL WAS SUBSEQUENTLY REDUCED TO ONE SUBUNIT ...Details: THE CRYSTAL PACKING WAS SOLVED USING MOLECULAR REPLACEMENT TECHNIQUES USING A DODECAMER MODEL FROM SALMONELLA TYPHIMURIUM GS AS A PROBE. THE MODEL WAS SUBSEQUENTLY REDUCED TO ONE SUBUNIT WITH 24-FOLD NCS-SYMMETRICAL CONSTRAINTS IMPOSED. THE SUBUNIT WAS REFINED WITH STRICT 24-FOLD NCS-AVERAGING CONSTRAINTS AND THEN USED TO REGENERATE THE ENTIRE ASYMMETRIC UNIT. AS JUSTIFIED BY LOWER R-VALUES, THE FOLLOWING RESIDUES WERE COMPLETELY RELEASED AT THE END OF THE REFINEMENT IN ORDER ACCOMMODATE CRYSTAL CONTACTS: RESIDUES 385,98,602,11,7,40,3,292.
