Biochemical characterizations and hydrolysis products analyses of recombinant XynAGN16L and XynAGN16Lpd showed similar features, including showing catalytic activities at 0 °C, thermolabilities at temperatures of more than 50 °C, and similar substrate specificity.  Compared with three thermophilic endoxylanases, XynAGN16L has a surface loop from A57 to Y77 and a decreased number of salt bridges.
