Complete 1H, 13C, 15N resonance assignments and secondary structure of the Vpr binding region of hHR23A (residues 223–363)
2019
Comprehensive resonance assignments and delineation of the secondary structure elements of the C-terminal Vpr-binding region of hHR23A, residues 223–363, were achieved by triple-resonance NMR experiments on uniformly 13C,15N-labeled protein. Assignments are 100% and > 95% complete for backbone and side-chain resonances, respectively. This data constitutes important complementary information for our ongoing structure determination of the Vpr-hHR23A(223–363) complex. At high concentrations, severe line-broadening was observed for several residues in the 1H–15N HSQC spectrum, most likely resulting from inter-molecular interactions.
