FIG 3 — Comparison of the two copies of the DH677.3 Fab-gp120_93TH057 core_e-M48U1 complex and the two Fab copies in the apo Fab structure from the asymmetric unit of crystals. (A) The root mean square deviation (RMSD) between complex copies is 0.946 Å for main-chain residues. (B) The RMSD between the Fab copies in the apo Fab structure is 0.540 Å for main-chain residues. (C) Comparison of the free and bound DH677.3 Fab. The α-carbon backbone diagram of superposition of the structures of DH677.3 Fab alone (dark cyan, heavy chain; light cyan, light chain) and N5-i5 Fab bound to CD4-triggered gp120 (dark brown, heavy chain; light brown, light chain). The average RMSD between free and bound Fabs is 0.818 Å for main-chain residues.
