(C) Cartoon diagram of the crystal structure of hCAP-G (orange) in complex with a fragment of hCAP-H (green). Unstructured, disordered regions are indicated by the dots. The 19 HEAT repeats (H1-H19) and 2 disordered loops (H12 loop and H15 loop) of hCAP-G, and 4 helices (α2, α3', α3" and α4) of hCAP-H are labeled. The N- and C termini of CAP-G and CAP-H are also indicated. A molecule of 4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid (HEPES) is shown by the orange-colored stick model. A 90-degree rotated version is shown on the right.
