NMR characterization of NS5A-D2 (JFH1). A, assigned
1H,15N HSQC spectrum of domain 2 of NS5A (JFH1). The
smaller insert shows the spectrum region corresponding to the two
tryptophan side chains. B, CSI analysis of NS5A-D2. NS5A-D2
13Cα, 13Cβ, and 13CO chemical
shifts were analyzed using CSI software
(54). The consensus CSI is
zero along the complete sequence and therefore is not shown.
