Note that RDC restraints were included only for the least mobile residues Ile-4 to Met-19 (with S2 > 0.65), dihedral restraints were included for residues Ile-4 to Ala-22, NOE and 3J_HNHA restraints were included for residues Val-2 to Met-24. Also note that the residue index in PDB and constraints files is such that HIV-1 gp41 fusion domain residue i is actually labeled as i+1.
