ANALYTICAL SIZE EXCLUSION CHROMATOGRAPHY WITH STATIC LIGHT SCATTERING SUGGESTS THAT A MONOMER IS A SIGNIFICANT OLIGOMERIZATION STATE IN SOLUTION. CRYSTAL PACKING ANALYSIS INDICATES THAT, IN ADDITION TO THE MONOMER, A DIMER MAY BE STABLE.
THE CONSTRUCT (RESIDUES 1-216) WAS EXPRESSED WITH A PURIFICATION TAG MGSDKIHHHHHHENLYFQG. THE TAG ...THE CONSTRUCT (RESIDUES 1-216) WAS EXPRESSED WITH A PURIFICATION TAG MGSDKIHHHHHHENLYFQG. THE TAG WAS REMOVED WITH TEV PROTEASE LEAVING ONLY A GLYCINE (0) FOLLOWED BY THE TARGET SEQUENCE.

A MET-INHIBITION PROTOCOL WAS USED FOR SELENOMETHIONINE INCORPORATION DURING PROTEIN EXPRESSION. THE OCCUPANCY OF THE SE ATOMS IN THE MSE RESIDUES WAS REDUCED TO 0.75 FOR THE REDUCED SCATTERING POWER DUE TO PARTIAL S-MET INCORPORATION. 2. CHLORIDE IONA (CL) FROM THE PROTEIN BUFFER SOLUTION ARE MODELED INTO THE STRUCTURE. 3. PHENIX.XTRIAGE ANALYSIS OF THE DIFFRACTION DATA REVEALS A SIGNIFICANT OFF-ORIGIN PATTERSON PEAK THAT IS 55.4% OF THE ORIGIN PEAK INDICATING PSEUDO-TRANSLATIONAL SYMMETRY RELATING PAIRS OF MONOMERS IN THE ASYMMETRIC UNIT. 4. ATOM RECORD CONTAINS SUM OF TLS AND RESIDUAL B FACTORS. ANISOU RECORD CONTAINS SUM OF TLS AND RESIDUAL U FACTORS. 5. NCS RESTRAINTS WERE APPLIED USING BUSTER'S LSSR RESTRAINT REPRESENTATION (-AUTONCS).
