Figure 3: SAXS measurements and structure models of TD4.
From: XTACC3–XMAP215 association reveals an asymmetric interaction promoting microtubule elongation
(a) Pair distance distribution function p(r) for TD4 alone (black) or with pCt (red) are shown together in an ab initio GASBOR34 model. (b) A TD4 dimer model with and without P2 symmetry is composed of four helices (α1–α4). The models were manually constructed and were optimized using CORAL38. The two models have also been turned 90° around two perpendicular axes to show different projections.
