| HADDOCK | REFINEMENT DETAILS CAN BE FOUND IN THE JRNL CITATION ABOVE. THE ENSEMBLE OF STRUCTURES IS SUPERIMPOSED ON THE CA OF NISIN RESIDUES 1-12 (CHAIN N), THE HEAVY ATOMS OF MURNAC, PYROPHOSPHATE AND THE FIRST ISOPRENE OF 3-LIPID II (CHAIN L) AS THESE ARE THE ONLY SEGMENTS THAT HAVE SUFFICIENT DISTANCE RESTRAINTS TO DEFINE THE COMPLEX STRUCTURE. OTHER RESIDUES NAMELY RESIDUES 13-34 (ESPECIALLY RESIDUES 20-34) OF NISIN, THE PENTAPEPTIDE AND TERMINAL ISOPRENE UNITS OF 3-LIPID II ARE FLEXIBLE AS SUPPORTED BY DYNAMICS DATA. THE ATOM OCCUPANCY OF THE C- TERMINAL TAIL OF NISIN (RESIDUES 20-34) HAS BEEN MODIFIED TO BE 0.3 TO REFLECT THEIR DISORDER/FLEXIBILITY. | CNS |

| Details | THE STRUCTURE WAS DETERMINED USING MULTIDIMENSIONAL NMR SPECTROSCOPY ON 15N-LABELLED NISIN IN COMPLEX WITH UNLABELLED 3-LIPID II. INTERMOLECULAR HYDROGEN BONDS WERE IDENTIFIED AND USED IN STRUCTURAL CALCULATION BY 31P- EDITED 1H-15N CT HSQC. |
