Fig. 2. Testosterone binding sites with omit electron density map (mFo–DFc map, calculated after 10 refinement cycles without testosterone, σ – 3.0) presented in green and red (positive and negative contours, respectively). TBS1 is located between subdomains IIA and IIB, while TBS2 is surrounded by subdomains IA and IB. Colors of helices correspond with the domains' colors in Fig. 5. The electron density can be inspected interactively at ; https://molstack.bioreproducibility.org/p/9CP6/.
