Glycosyl hydrolase enzymes and compositions comprising such enzymes, and methods of using the enzymes and compositions to saccharify or convert cellulosic and hemicellulose materials into sugars. A first polypeptide having β-xylosidase activity or a variant thereof, wherein the Fv3A polymorph has at least 90% sequence identity to a specific amino acid sequence or a specific residue of the specific sequence. A non-natural composition comprising a first polypeptide or variant that is a peptide and a second polypeptide having xylase activity. Preferably, the non-natural composition further comprising a third polypeptide having L-α-arabinofuranosidase activity or a variant thereof. [Selection figure] None |
