Category STRUCT_SHEET_RANGE

Name:
'struct_sheet_range'

Description:

   Data items in the STRUCT_SHEET_RANGE category record details
   about the residue ranges that form a beta-sheet. Residues are
   included in a range if they made beta-sheet-type hydrogen-bonding
   interactions with at least one adjacent strand and if there are
   at least two residues in the range.

Examples:

Example 1 - simple beta-barrel.
