Multiple sequence alignment of xylanase protein sequence (a) and its predicted structure (b). Xylanase-encoding protein sequences retrieved from NCBI were aligned with xylanase sequences of thermophilic isolates using BioEdit sequence editor (Version 7.2.5). The consensus symbols ‘*’ means residues are identical, ‘:’ means conserved substitutions, ‘.’ means semi-conserved substitutions in the alignment. The active site region is shown in blue boxes. The structure was predicted in the Swiss-Homology Modeling server and the active sites are indicated
