Although the current models fit well with both RDCs and SAXS, sf3636 may sample a range of relative domain orientations depending on data types and refinement tools. To further investigate sf3636 domain orientation and its intrinsic dynamic nature, Prestegard lab is developing a new protocol using RCSAs and RDCs from several mediums. Their refined models will be deposited later.
