CONSTRUCTION OF BACTERIOPHAGE MODEL BASED ON THE SOLID STATE NMR STRUCTURE OF THE MAJOR COAT PROTEIN MONOMERSIDECHAINS WERE ADDED TO THE SOLID STATE NMR BACKBONE STRUCTURE USING THE PROGRAM SCWRL. A BACTERIOPHAGE MODEL WAS CONSTRUCTED BY APPLYING PUBLISHED X- RAY FIBER AND NEUTRON DIFFRACTION SYMMETRY AND DISTANCE CONSTRAINTS (INITIAL PHAGE), WHICH WAS FURTHER REFINED BY COMPARING THE REPULSIVE AMBER ENERGY (USING SCWRL) OF MANY CONFIGURATIONS IN WHICH THE MONOMERS HAD BEEN SYMMETRICALLY ROTATED AND TRANSLATED WITH RESPECT TO THE INITIAL PHAGE.MATLAB SCRIPTS 6.5, SCWRL

Representative Model (nearest structure to the average of the 60 best ramachandran structures (based on a statistical ramachandran potential) out of 1000 total structures.)
Additional NMR Experimental Information
DetailsMODEL 1 IS THE BASIC SOLID-STATE NMR STRUCTURE (NO SIDECHAINS), WHILE MODELS 2-27 ARE IDENTICAL TRANSLATED AND ROTATED COPIES OF MODEL 1 (WITH SIDECHAINS ADDED AND ENERGY MINIMIZED) INCLUDED TO PRESENT THE MODEL OF THE WHOLE BACTERIOPHAGE ASSEMBLY.
