Abstract:

Structural biology has been paying more attention on biomolecular complexes over the past decades, since they are crucial for many biological processes. Among these techniques for structural determination, nuclear magnetic resonance (NMR) has its advantage when dealing with biomolecules with high flexibility in solution. Small-angle X-ray scattering (SAXS) is a very important complementary technique that provides information on global shape of biomolecules. For biomolecular complexes, it can be much easier to determine atomic structures of individual subunits through NMR. In addition, NMR can also provide other structural information, such as the interface and orientations between subunits, and long range distance and angular restraints. Therefore, to construct structural models of biomolecular complexes, it would be very appropriate to combine experimental restraints obtained through NMR and low-resolution shape information from SAXS by utilizing computational tools, which is the main topic of this review.
