Figure 2. Fig. 2. Structure of the Ca^2+-S100B-TRTK-12 complex. The N and C termini are labeled for one S100 monomer and TRTK-12, and helices are indicated for S100 . A, stereo view of the backbone superposition of the final ensemble of 17 NMR derived structures of the complex. S100 monomers are shown in magenta and blue, and the TRTK-12 peptide molecules are shown in light blue. B, ribbon structure of the complex. Each monomer consists of four -helices (helix I, blue; II, magenta; III, green; and IV, yellow) and two anti-parallel -strands (orange, blue). TRTK-12 is shown in dark blue.
