distance geometry
DISTANCE GEOMETRY WAS PERFORMED USING 5%-PAIRWISE METRIZATION AND A GAUSSIAN TRIAL DISTRIBUTION FOR THE SELECTION OF DISTANCES USING THE PROGRAM DISTGEOM, A COMPONENT OF THE TINKER MOLECULAR MODELING PACKAGE. EMBEDDED STRUCTURES WERE REFINED VERSUS A PENALTY FUNCTION BASED SOLELY ON THE EXPERIMENTAL RESTRAINTS AND LOCAL COVALENT GEOMETRY (BOND LENGTHS, ANGLES, CHIRALITY) OBTAINED FROM A EXTENDED MODEL GENERATED BY QUANTA; NO ENERGY-BASED TERMS WERE INCLUDED. DETAILS OF THE CALCULATIONS AND STRUCTURAL STATISTICS ARE GIVEN IN THE JRNL RECORDS ABOVE.
