Figure 3From: The Host-Pathogen interaction of human cyclophilin A and HIV-1 Vpr requires specific N-terminal and novel C-terminal domainsMutation of Arg-80 with Ala does not influence the secondary structure of Vpr75-90. Chemical shift differences (ppm) of the α-protons between the experimental values and those for residues in a random coil for Vpr75-90 (A) and s Vpr75-90 R80A (B) in H2O-D2O 9:1 (v/v) containing 100 mM DPC-d38 at 300 K.Back to article page
