Data items in the PDBX_STRUCT_SHEET_HBOND category record details
           about the hydrogen bonding between residue ranges in a beta sheet.
           This category is provided for cases where only a single hydrogen
           bond is used to register the two residue ranges.   Category
           STRUCT_SHEET_HBOND should be used when the initial and terminal
           hydrogen bonds for strand pair are known.
