Gene Expression and Molecular Characterization of a Xylanase from Chicken Cecum Metagenome

Figure 3

Structure of modeled using crystal structure of a closely related GH10 endo-xylanase (2cnc.1.A) as a template. (a) Predicted secondary structure of ; purple box: alpha-helix; green arrow: beta-sheet. (b, c) Three-dimensional representation of with alpha-helices, beta-sheets, and loops folded into the typical (β/α)₈ TIM-barrel structure; (b) top view; (c) side view. The xylanase is shown with 2 molecules of β-D-xylopyranose (stick models) on the catalytic face.
