The 1H, 15N and 13C resonance assignments of dengue virus capsid protein with the deletion of the intrinsically disordered N-terminal region

Dengue virus belongs to the Flaviviridae family, being responsible for an endemic arboviral disease in humans. It is an enveloped virus, whose genome is a positive-stranded RNA packaged by the capsid protein. Dengue virus capsid protein (DENVC) forms homodimers in solution organized in 4 α-helices and an intrinsically disordered N-terminal region. The N-terminal region is involved in the binding of membranous structures in host cells and in the recognition of nucleotides. Here we report the ¹H, ¹⁵N and ¹³C resonance assignments of the DENVC with the deletion of the first 19 intrinsically disordered residues. The backbone chemical shift perturbations suggest changes in the α1 and α2 helices between full length and the truncated proteins.
