Category Description
Data items in the STRUCT_SHEET_TOPOLOGY category record details
about the topology of the residue ranges that form a beta sheet.
All topology linkages are pairwise, and the specified pairs are
assumed to be successive in the amino acid sequence. These
data items are useful in describing various simple and complex
folds, but they become inadequate when the strands in the sheet
come from more than one chain. One can alternatively use the
STRUCT_SHEET_ORDER data items to describe both single and
multiple chain-containing sheets.
