Photo of The structure model of the new glycoside hydrolase family 30-8 (GH30-8) xylanase (green) overlaid with the previously determined protein structure of a canonical GH30-8 xylanase (blue) indicating that although the new xylanase is functionally unique, it does not structurally differ from the canonical GH30-8 xylanases (top). An alignment showing the specific region of primary amino acid sequence containing the altered sequence (red boxes) attributed to the observed difference in mode of action of this new enzyme against its xylan substrate.
