BIOMOLECULE: 1, 2, 3, 4, 5, 6 THIS ENTRY CONTAINS THE CRYSTALLOGRAPHIC ASYMMETRIC UNIT WHICH CONSISTS OF 6 CHAIN(S). SEE REMARK 350 FOR INFORMATION ON GENERATING THE BIOLOGICAL MOLECULE(S). SIZE EXCLUSION CHROMATOGRAPHY WITH STATIC LIGHT SCATTERING SUPPORT THE ASSIGNMENT OF A MONOMER AS A BIOLOGICALLY SIGNIFICANT OLIGOMERIZATION STATE.
SEQUENCE THE CONSTRUCT WAS EXPRESSED WITH A PURIFICATION TAG MGSDKIHHHHHHENLYFQG. THE TAG WAS REMOVED WITH TEV PROTEASE LEAVING ONLY A GLYCINE (0) FOLLOWED BY THE TARGET SEQUENCE.
1. HYDROGENS HAVE BEEN ADDED IN THE RIDING POSITIONS. 2. ATOM RECORD CONTAINS RESIDUAL B FACTORS ONLY. 3. 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. 4. CALCIUM AND ACETATE FROM THE CRYSTALLIZATION SOLUTIONS WERE MODELED INTO THE STRUCTURE. 5. ETHYLENE GLYCOL USED AS A CRYOPROTECTANT WAS MODELED INTO THE STRUCTURE. 6. UNEXPLAINED DIFFERENCE ELECTRON DENSITIES NEAR GLY 112 IN THE D AND E SUBUNITS WERE NOT MODELED. 7. ARG B205, PHE B207, ASP C35, AND PRO C36 WERE MODELED INTO ELECTRON DENSITY BUT ARE RAMACHANDRAN OUTLIERS.
SIZE EXCLUSION WITH STATIC LIGHT SCATTERING SUPPORTS THE ASSIGNMENT OF A MONOMER AS A BIOLOGICALLY SIGNIFICANT OLIGOMERIZATION STATE.
