Multiple sequence alignment of C-terminal module (amino acids 340–559) of Cel14b22 with xylanase/cellulase (1923215A, 375-584aa) from the ruminal bacterium Prevotella ruminicola 23 and uncultured ruminal microbial cellulases (ACA61137, aa 334–546; ACA61140, aa 334–537; ABB46200, aa 715–917; ADA 62505, aa 721–919). The nine conserved aromatic amino acid residues among homologous C-terminal modules are highlighted in bold and blue.
