<xsd:documentation xml:lang="en">Data items in the STRUCT_SHEET_ORDER category record details about the order of the residue ranges that form a beta-sheet. All order links are pairwise and the specified pairs are assumed to be adjacent to one another in the sheet. These data items are an alternative to the STRUCT_SHEET_TOPOLOGY data items and they allow all manner of sheets to be described. Example 1 - simple beta-barrel. <PDBx:struct_sheet_orderCategory> <PDBx:struct_sheet_order range_id_1="strand_a" range_id_2="strand_b" sheet_id="sheet_1"> <PDBx:offset>+1</PDBx:offset> <PDBx:sense>parallel</PDBx:sense> </PDBx:struct_sheet_order> <PDBx:struct_sheet_order range_id_1="strand_b" range_id_2="strand_c" sheet_id="sheet_1"> <PDBx:offset>+1</PDBx:offset> <PDBx:sense>parallel</PDBx:sense> </PDBx:struct_sheet_order> <PDBx:struct_sheet_order range_id_1="strand_c" range_id_2="strand_d" sheet_id="sheet_1"> <PDBx:offset>+1</PDBx:offset> <PDBx:sense>parallel</PDBx:sense> </PDBx:struct_sheet_order> <PDBx:struct_sheet_order range_id_1="strand_d" range_id_2="strand_e" sheet_id="sheet_1"> <PDBx:offset>+1</PDBx:offset> <PDBx:sense>parallel</PDBx:sense> </PDBx:struct_sheet_order> <PDBx:struct_sheet_order range_id_1="strand_e" range_id_2="strand_f" sheet_id="sheet_1"> <PDBx:offset>+1</PDBx:offset> <PDBx:sense>parallel</PDBx:sense> </PDBx:struct_sheet_order> <PDBx:struct_sheet_order range_id_1="strand_f" range_id_2="strand_g" sheet_id="sheet_1"> <PDBx:offset>+1</PDBx:offset> <PDBx:sense>parallel</PDBx:sense> </PDBx:struct_sheet_order> <PDBx:struct_sheet_order range_id_1="strand_g" range_id_2="strand_h" sheet_id="sheet_1"> <PDBx:offset>+1</PDBx:offset> <PDBx:sense>parallel</PDBx:sense> </PDBx:struct_sheet_order> <PDBx:struct_sheet_order range_id_1="strand_h" range_id_2="strand_a" sheet_id="sheet_1"> <PDBx:offset>+1</PDBx:offset> <PDBx:sense>parallel</PDBx:sense> </PDBx:struct_sheet_order> </PDBx:struct_sheet_orderCategory> Example 2 - five stranded mixed-sense sheet with one two-piece strand. <PDBx:struct_sheet_orderCategory> <PDBx:struct_sheet_order range_id_1="strand_a" range_id_2="strand_b" sheet_id="sheet_2"> <PDBx:offset>+1</PDBx:offset> <PDBx:sense>anti-parallel</PDBx:sense> </PDBx:struct_sheet_order> <PDBx:struct_sheet_order range_id_1="strand_b" range_id_2="strand_c" sheet_id="sheet_2"> <PDBx:offset>+1</PDBx:offset> <PDBx:sense>parallel</PDBx:sense> </PDBx:struct_sheet_order> <PDBx:struct_sheet_order range_id_1="strand_c" range_id_2="strand_d1" sheet_id="sheet_2"> <PDBx:offset>+1</PDBx:offset> <PDBx:sense>anti-parallel</PDBx:sense> </PDBx:struct_sheet_order> <PDBx:struct_sheet_order range_id_1="strand_c" range_id_2="strand_d2" sheet_id="sheet_2"> <PDBx:offset>+1</PDBx:offset> <PDBx:sense>anti-parallel</PDBx:sense> </PDBx:struct_sheet_order> <PDBx:struct_sheet_order range_id_1="strand_d1" range_id_2="strand_e" sheet_id="sheet_2"> <PDBx:offset>+1</PDBx:offset> <PDBx:sense>anti-parallel</PDBx:sense> </PDBx:struct_sheet_order> <PDBx:struct_sheet_order range_id_1="strand_d2" range_id_2="strand_e" sheet_id="sheet_2"> <PDBx:offset>+1</PDBx:offset> <PDBx:sense>anti-parallel</PDBx:sense> </PDBx:struct_sheet_order> </PDBx:struct_sheet_orderCategory></xsd:documentation>
