Alignment of P33 xylanases with different heterologous xylanases. a Alignment of Xyl1 and Xyl3 with different GH10 xylanase; b Alignment of Xyl2 with different GH11 xylanases. The catalytic residues were marked with *, the residues in the gray colored boxes are the CBM1 residues and the residues in the box is the loop of Xyl3
