Details

The full-length Sgt2 structure was determined entirely based on experimental NMR data collected for the full-length protein. We performed extensive NMR experiments on the full-length Sgt2, obtaining complete backbone, side-chain, and methyl group assignments, as well as NOE restraints, for all three domains (N,TPR and C). Both our NMR and biochemical data indicate that the three domains behave independently and do not form stable inter-domain contacts, resulting in a highly dynamic,"beads-on-a-string" architecture. This is supported by the absence of long-range inter-domain NOEs, as well as by extensive NMR spectral overlay and SAXS data, all of which reflect the true solution behavior of the protein.
