Figure 4
Superimposition of the MSBI1.176 WH1 β2–β3 hairpin onto prokaryotic Rep proteins with PDB codes 1hkq (RepA) and 2z9o (RepE). The MSBI1.176 WH1 β2–β3 hairpin shifted approximately 23 Å when compared with the equivalent RepA hairpin. The MSBI1.176 WH1 β2–β3 hairpin was held by direct main-chain interactions (Fig. 3[link]a) as well as water-mediated interactions. Note the different β2–β3 hairpin twists between the MSBI1.176 and RepA WH1 structures in Fig. 3[link](a). The RepE β2–β3 hairpin was positioned between these two WH1 β2–β3 hairpins.
