THE TAG WAS REMOVED WITH TEV PROTEASE LEAVING ONLY A GLYCINE (0) FOLLOWED BY THE TARGET SEQUENCE. 2. THIS GENE USES AN ALTERNATE INITIATION CODON THAT RESULTS IN A VALINE AT POSITION 1 WHEN EXPRESSED AS A FUSION WITH THE PURIFICATION TAG.

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. SULFATE (SO4), MAGNESIUM (MG) FROM CRYSTALLIZATION CONDITION AND CHLORIDE (CL) FROM THE PROTEIN BUFFER ARE MODELED INTO THE STRUCTURE 3. ATOM RECORD CONTAINS SUM OF TLS AND RESIDUAL B FACTORS. ANISOU RECORD CONTAINS SUM OF TLS AND RESIDUAL U FACTORS. 4. WATERS WERE EXCLUDED FROM AUTOMATIC TLS ASSIGNMENT. 5. SAD EXPERIMENTAL PHASES WERE USED AS RESTRAINTS DURING REFINEMENT.
