Figure 7.
FIG. 7. Solution structure characterization of HNTX-IV. A,
surface profile of HNTX-IV. a, surface profile of predicted
active sites. b, surface profile of putative active sites. Blue,
mauve, and cyan regions represent positively charged, polar, and
hydrophobic residues, respectively. B, backbone superposition of
native HNTX-IV (blue), K27A (green), and R29A (red). 27 and 29
indicate the positions of substituted amino acid residues. The
fit was done using the common secondary structure elements. The
letters N and C refer to the amino and carboxyl termini,
respectively.
