Structural comparisons of B. brevis xylanase with other Bacillus Sp. (A). Surface view of Xylanase protein 3D structure, (B). Superimposition of two B. brevis structures, Green regions shows differences in the amino acid sequences of the two structures. Three differences are around active site while two are grouped at the distant region of the proteins. (C & D). Superimposition with B. licheniformis and B. amyloliquefaciens xylanse 3D structures respectively.
