| 概 要 | I shall present algorithms to detect and visualize the secondary structural elements (helices and sheets) of proteins for which the reconstructed 3D Electron Microscopy (EM) maps are at 5-10 Angstrom resolution. Additionally, I shall show that for 3D EM maps at coarser than 10 Angstrom resolution, some of the tertiary structural motifs can be detected. For each of these algorithms, one employs tools from computational geometry and differential topology, specifically the computation of stable/unstable manifolds of certain critical points of the distance function induced by the molecular surface. I shall finally indicate an approach we are calibrating of estimating molecular properties as well, from reconstructed 3D EM. 過去のＣＭＳセミナーはこちらでご覧いただけます |
