Structure of CAMP factor within MBP-CAMP crystals. (a) Single hexagonal pyramid-shaped crystals of MBP-CAMP. The crystals reached a size of 0.2–0.4 mm in each dimension after two weeks at 18°C. (b) A typical diffraction image of MBP-CAMP. (c) Cartoon representation of CAMP factor. Its N- and C-termini and eight helices are labeled. (d) Topology of CAMP factor. It has two well separated domains composed of five and three helices.
