Relaxed-eyed stereo views of the 15 ns model. (a) Mapping of the location of the five helical domains predicted by Chetty et al. using H/D exchange⁴⁰ onto a relaxed-eyed stereo ribbon representation of the 15 ns model. Helical domains [marked as 1–5 (see Figure 3a)] of the 15 ns model predicted to be helical are colored red and helical domains of the 15 ns model predicted not to be helical are green. The remainder of the nonhelical structure is colored gray. Prolines are shown as yellow spheres. The N-terminus is marked with a yellow N and the C-terminus with a red C. (b) Cartoon representation of the 15 ns model in same orientation as panel a. Helical domains are represented as cylinders and nonhelical domains as random coils. Color code: H5, green; H10, red; N-terminal helical domain, yellow; other helical domains, magenta; K40 and Y192, cyan and magenta spheres, respectively. The N- and C-termini are indicated as in panel a.
