Figure 5.

Involvement of the β-bridge in macromolecular interactions. The coloring of helix-strand-helix motifs is as in Fig. 2, except the β-bridges are colored red. (A) The histone H3-H4 complex bound to DNA (1S32); residues of the β-bridges engaged in interactions with the phosphate backbone are shown in stick representation. (B) ClpS in complex with ClpA (1LZW, 1R6B); the ATPase domain is in light blue and ClpS in cyan.
