THE BIOLOGICAL UNIT WAS DETERMINED BY COMBINED APPROACH OF COMPUTATIONAL DESIGN, ANALYTICAL ULTRACENTRIFUGATION AND 19F-CODEX VIA SOLID-STATE NMR. AS PER THE AUTHORS THIS TETRAMERIC ASSEMBLY IS REPORTED IN THE SEPARATE ENTRY (PDB ID: 2MUZ) FOR THE SOLID-STATE NMR MODEL ACCOMPANIED BY THE PAPER THAT CITES THIS PDB
BR HAS ZERO OCCUPANCY IN 4BF. THE AUTHORS COLLECTED DATA FROM THE SINGLE CRYSTAL USING THE ...BR HAS ZERO OCCUPANCY IN 4BF. THE AUTHORS COLLECTED DATA FROM THE SINGLE CRYSTAL USING THE SYNCHROTRON BEAM TUNED AT THE BROMINE EDGE. BROMINE IS VERY LABILE UNDER RADIATION AND READILY DEGRADES UPON REPEATED DATA COLLECTION. THE LAST DATASET IS COLLECTED BY USING INCREASED EXPOSURE TO ATTAIN DIFFRACTIONS AT THE HIGH-RESOLUTION SPACE. THIS RESULTS IN OCCUPANCY OF 0 FOR THE MENTIONED BROMINE. THIS STUDY HAS BEEN CONFIRMED BY MASS SPEC
