BIOMOLECULE: 1 SEE REMARK 350 FOR THE AUTHOR PROVIDED AND PROGRAM GENERATED ASSEMBLY INFORMATION FOR THE STRUCTURE IN THIS ENTRY. SIZE EXCLUSION CHROMATOGRAPHY SUPPORTS THE ASSIGNMENT OF A MONOMER AS THE SIGNIFICANT OLIGOMERIZATION STATE.
SEQUENCE THE CONSTRUCT WAS EXPRESSED WITH A PURIFICATION TAG MGSDKIHHHHHHENLYFQG. THE TAG WAS REMOVED WITH TEV PROTEASE LEAVING ONLY A GLYCINE FOLLOWED BY THE TARGET SEQUENCE.
1. HYDROGENS HAVE BEEN ADDED IN THE RIDING POSITIONS. 2. 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 TO ACCOUNT FOR THE REDUCED SCATTERING POWER DUE TO PARTIAL S-MET INCORPORATION. 3. ATOM RECORD CONTAINS RESIDUAL B FACTORS ONLY. 4. SEVEN PG4 AND ONE TRIS MOLECULE(S) HAVE BEEN MODELED IN THE SOLVENT STRUCTURE.
SIZE EXCLUSION CHROMATOGRAPHY SUPPORTS THE ASSIGNMENT OF A MONOMER AS THE SIGNIFICANT OLIGOMERIZATION STATE.
