FIGURE 2

Predicted 3-D structure of XynSPP2. XynSPP2 consists of an N-terminal Fn3 domain (yellow) and a C-terminal GH10 domain (gray). Overall structural architecture of XynSPP2 is presented as cartoon (left) and surface (middle) models. Amino acids constituting the active-site cleft of XynSPP2 are shown in green stick (right). Subsites in the active-site cleft are indicated by magenta numbers.
