THIS ENTRY CONTAINS THE CRYSTALLOGRAPHIC ASYMMETRIC UNIT
WHICH CONSISTS OF 4 CHAIN(S). SEE REMARK 350 FOR
INFORMATION ON GENERATING THE BIOLOGICAL MOLECULE(S).
SIZE EXCLUSION CHROMATOGRAPHY SUPPORTS THE ASSIGNMENT
OF A DIMER AS A BIOLOGICALLY SIGNIFICANT
OLIGOMERIZATION STATE.

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. CA ATOMS MODELED BASED ON DENSITY AND GEOMETRY. 5. MSE B1 AND ILE 193 FROM ALL CHAINS ARE RAMACHANDRAN OUTLIERS. ALL ARE SUPPORTED BY THE ELECTRON DENSITY. 6. RESIDUES 297-300 FROM CHAINS A AND B, AND RESIDUES 298-300 FROM CHAINS C AND D WERE NOT MODELED DUE TO LACK OF DENSITY.
