REMARK 3 REMARK 3 THE PLANARITY OF THE PEPTIDE BOND WAS RELAXED FOR RESIDUES REMARK 3 190-194 BECAUSE IT WAS THE ONLY WAY THE MODEL COULD BE REMARK 3 FITTED INTO THE DENSITY. THE DENSITY WAS CONTINUOUS REMARK 3 THROUGH THIS REGION, AND SO THE AUTHORS CHOSE TO MODEL REMARK 3 INTO THE DENSITY RATHER THAN TO PRESERVE THE REQUIREMENT REMARK 3 FOR PLANARITY OF OMEGA. REMARK 3 REMARK 3 COORDINATES FOR RESIDUES -1, 0, AND 1 - 3 ARE NOT INCLUDED REMARK 3 IN THIS ENTRY BECAUSE THESE RESIDUES COULD NOT BE RESOLVED REMARK 3 IN THE FINAL ELECTRON DENSITY MAPS.
