REMARK 3 REMARK 3 REFINEMENT. REMARK 3 PROGRAM : NULL REMARK 3 AUTHORS : NULL REMARK 3 REMARK 3 OTHER REFINEMENT REMARKS: THE MODEL WITH THE LOWEST MODELLER REMARK 3 TARGET FUNCTION WAS CHOSEN. IT WAS OPTIMIZED BY ADDITIONAL REMARK 3 REFINEMENT OF LOOP REGIONS AND MANUAL TRACING OF SIDE CHAINS REMARK 3 IN THE ACTIVE CENTER IN ORDER TO MAXIMIZE CONTACTS WITH THE REMARK 3 LIGANDS. NO SEVERE DISALLOWED ATOMIC CONTACTS WERE DETECTED REMARK 3 WITH WHATIF, AND PROCHECK REVEALED ESSENTIALLY GOOD REMARK 3 STEREOCHEMISTRY (87% AND 13% OF THE RESIDUES IN THE MOST REMARK 3 FAVOURED AND ADDITIONAL ALLOWED REGIONS, RESPECTIVELY OF THE REMARK 3 RAMACHANDRAN PLOT). VERIFY3D YIELDED A SCORE OF 0.21.
