List of order parameters

d_C-C	Distance between CA atoms of residues 43 in the two monomers.
d_H-O	Distance between hydrogen atom HG in the side chain of residue 21 (Cys/Ser) and oxygen atom O in the backbone of residue Gln¹⁷.
d_i-j'	Distance between centers of mass of the side chains of residues at positions i and j in the other monomer, indicated by the prime symbol (′). These distances are calculated for the following pairs:
	(Antiparallel) Leu²⁶-Val^37′, Leu³⁰-Leu^33′, Leu³³-Leu^30′, and Val³⁷-Leu^26′,
	(Parallel) Leu²⁶-Leu^26′, Leu³⁰-Leu^30′, Leu³³-Leu^33′, and Val³⁷-Val^37′.
N-H–O=C	Distance between hydrogen atom H in the backbone of residue n and oxygen atom O in the backbone of residue n+4.
Σnhc	Sum of distances of native hydrophobic contacts. These distances include d_26-37′, d_30-33′, d_33-30′, and d_37-26′ for the antiparallel conformation, and d_26-37′, d_30-33′, d_33-30′, and d_37-26′ for the parallel conformation.
Σα1	Sum of distances of N-H – O=C of residues 2–6, 3–7, and 4–8.
Σα2	Sum of distances of N-H – O=C of residues 10–14, 11–15, 12–16, and 13–17.
Σ_8-14-33	Sum of distances of centers of mass of side chains of residues Leu⁸, Leu¹⁴, and Leu³³.
