Comparison of family GH10 endoglycanases. The amino acid sequence of XYL-6p was deduced from the five exons encoded by the XYL-6 gene (GenBank accession number AY124591) and compared, using software programs included in the Wisconsin Package (Genetics Computer Group, Madison, WI), to M. grisea XYL-2 (formerly XYN33) (35) and a putative endo-β-1,4-glycanase from Fusarium oxysporum (Glyfo) (28, 29). Identical amino acid residues among the compared sequences are highlighted.
