Fiber-like association of CMPs mediated by metal-ligand coordination. Fe2+ brings together three CMP triple helices by coordinating with Bpys incorporated into the CMP’s central amino acids: Structures of single strand CMP with central Bpy (A) and corresponding homotrimeric triple helix (B), and lateral CMP association by Fe2+ coordinating to three CMP triple helices (C).
