Results include individual domain (4) fitting and lobe (2) fitting. Four subdomains are defined as in Fig 1. Lobe 1 includes IA and IB, and lobe 2 includes IIA and IIB. Szz, the largest component of the alignment tensor; α, β, and γ, the Euler angles, which define the orientation of the alignment tensor in the frame of the PDB x-ray structure coordinates (PDB ID code 3HSC); rms, rms deviation of the |D_cal — D_exp|; R_svd, the correlation coefficient of singular value decomposition analysis; Q, the quality factor (24).
