Category Description
Data items in the STRUCT_SHEET_HBOND category record details
about the hydrogen bonding between residue ranges in a beta
sheet. It is necessary to treat hydrogen bonding independently
of the designation of ranges, because the hydrogen bonding may
begin in different places for the interactions of a given strand
with the one preceding it and the one following it in the sheet.
