FIG 1.

MSA of GH 10 xylanases with various temperature optima using the ClustalW program. TmxB, the xylanase from Thermotoga maritima; TpXyl10B, xylanase 10b from Thermotoga petrophila RKU-1; XYL10C, the endo-β-1,4-xylanase from Bispora sp. MEY-1; XylA, the β-1,4-endoxylanase from Thermobifida alba; XylE, the endo-1,4-xylanase from Penicillium canescens; XynC, the xylanase from Phanerochaete chrysosporium; and XynAS9, the xylanase from Streptomyces sp. S9. The catalytic residues are indicated with asterisks. The mutation sites are gray.
