Figure 5: 3D architecture of BmSUH showing positive selection and functional divergence residues.

Figure 5

(A) Tertiary structure of BmSUH that binds to sucrose (complex colored in grey). Critical sites that predicted to be involved in ligand binding are mapped onto the structure and are represented as stick model. (B) Nine sites both contributed to positive selection and FD I are mapped onto the tertiary structure of BmSUH with black sticks. α-Helices, β-sheets and turns are shown in magenta, yellow and pale blue, respectively. All other residues are shown in white.
