THE SEQUENCE WAS USED AS INPUT FOR REMARK 3 ALPHAFOLD2 PREDICTION WITH THE FIVE DEFAULT MODEL PARAMETERS AND REMARK 3 A TEMPLATE DATE CUTOFF OF 2020-05-14. AS THE FIVE MODELS WERE REMARK 3 LARGELY IDENTICAL IN THE CORE REGION AND DIFFERING ONLY IN THE REMARK 3 LOCATION OF THE C-TERMINAL TAIL, THE STRUCTURE PREDICTED WITH REMARK 3 THE FIRST MODEL PARAMETER WAS USED IN THE SUBSEQUENT PROCESS. REMARK 3 THE PREDICTED STRUCTURE WAS FIRST PROCESSED AND DOCKED INTO THE REMARK 3 UNSHARPENED MAP IN PHENIX. THE 25 N-TERMINAL RESIDUES AND 45 C- REMARK 3 TERMINAL RESIDUES WERE THEN MANUALLY REMOVED DUE TO LACK OF CRYO- REMARK 3 EM DENSITY, AND RESIDUES 26-426 WERE RETAINED IN THE MODEL. WE REMARK 3 OBSERVED UNMODELED DENSITY AT THE SPECIFICITY SITE, AND BASED ON REMARK 3 SOLUTION COMPOSITION, WE MODELED A TTP MOLECULE. THE TTP REMARK 3 MOLECULE WITH MAGNESIUM ION FROM THE CRYSTAL STRUCTURE OF REMARK 3 BACILLUS SUBTILIS RNR (PDB: 6MT9) WAS EXTRACTED AND RIGID BODY REMARK 3 FIT INTO THE UNMODELED DENSITY IN COOT. THE COMBINED MODEL WAS REMARK 3 REFINED WITH THE UNSHARPENED AND SHARPENED MAPS USING REMARK 3 PHENIX.REAL_SPACE_REFINE, WITH A CONSTRAINT APPLIED ON THE REMARK 3 MAGNESIUM ION COORDINATED BY THE TRIPHOSPHATE IN TTP ACCORDING REMARK 3 TO THE ORIGINAL CONFIGURATION. RESIDUE AND LOOP CONFORMATIONS IN REMARK 3 THE RESULTING STRUCTURE WERE MANUALLY ADJUSTED IN COOT TO REMARK 3 MAXIMIZE FIT TO MAP AND INPUT FOR AN ADDITIONAL ROUND OF REAL- REMARK 3 SPACE REFINEMENT IN PHENIX WITH AN ADDITIONAL RESTRAINT FOR THE REMARK 3 DISULFIDE BOND BETWEEN C30 AND C196. DUE TO POOR DENSITY OF THE REMARK 3 MAGNESIUM ION, IT WAS REMOVED WHEN DEPOSITED INTO PDB.
