Figure 3. — Crystal structure of p204 HINab:dsDNA complex. (A) Overall structure of p204 HINab:dsDNA complex. There are three p204 HINab molecules binding to two copies of dsDNA. Molecule A is shown in orange (HINa) and slate (HINb). Molecule B is shown in pink (HINa) and cyan (HINb). Molecule C is shown in yellow orange (HINa) and light blue (HINb). Two copies of dsDNA are shown in gray. (B) Similar DNA-binding mode of p204 HINa and HINb. Structures of HINa:dsDNA and HINb:dsDNA in p204 HINab:dsDNA complex were aligned, the position of dsDNA are conserved with slight bending. The DNA-binding surface formed by α2, C-termini of HINa, and N-termini of HINb, were showed in the relevant position. dsDNAs are shown in the same colour as the bound HINa or HINb. (C) Structural superposition of p204 HINa (violent), HINb (lime) and HINab:dsDNA.
