NOVELTY - Isolated polypeptide, which is: e.g. (a) a polypeptide comprising the amino acid sequence of any one of SEQ ID NOs: 389-582, 883-1032, and 1373-1542; (b) a polypeptide comprising an amino acid sequence having at least 60%, preferably at least 99% amino acid sequence identity to the polypeptide defined in (a); and (c) a polypeptide comprising an amino acid sequence encoded by the nucleic acid sequence of any one of SEQ ID NOs: 195-388, 733-882, and 1203-1372, is new.    USE - The polypeptide is useful for: the preparation or processing of a food product i.e. a bakery product; the preparation of animal feed; increasing digestion or absorption of animal feed i.e. a cereal-based feed; the production or processing (i.e. pre-bleaching or de-inking) of kraft pulp or paper; processing lignin; producing ethanol; treating textiles or dyed textiles; and degrading biomass or pretreated biomass (all claimed).    ADVANTAGE - The isolated polypeptide has improved thermostablity.    DETAILED DESCRIPTION - Isolated polypeptide which is: (a) a polypeptide comprising the amino acid sequence of any one of SEQ ID NOs: 389-582, 883-1032, and 1373-1542; (b) a polypeptide comprising an amino acid sequence having at least 60%, preferably at least 99% amino acid sequence identity to the polypeptide defined in (a); (c) a polypeptide comprising an amino acid sequence encoded by the nucleic acid sequence of any one of SEQ ID NOs: 195-388, 733-882, and 1203-1372; (d) a polypeptide comprising an amino acid sequence encoded by any one of the exonic nucleic acid sequences corresponding to the positions as defined in Tables 2A-2C of the specification; (e) a polypeptide comprising an amino acid sequence encoded by a polynucleotide molecule that hybridizes under medium-high stringency conditions, high stringency conditions, or very high stringency conditions with the full-length complement of a polynucleotide molecule comprising the nucleic acid sequence defined in (c) or (d); (f) a polypeptide comprising an amino acid sequence encoded by a polynucleotide molecule having at least 60%, preferably at least 99% nucleic acid sequence identity to a polynucleotide comprising the nucleic acid sequence defined in (c) or (d); (g) a functional variant of the polypeptide defined in (a) comprising a substitution, deletion, and/or insertion at one or more residues; or (h) a functional fragment of the polypeptide of any one of (a)-(g), is new.

INDEPENDENT CLAIMS are included for:    (1) an antibody that specifically binds to the isolated polypeptide;    (2) an isolated polynucleotide molecule, which encodes the polypeptide, or is (a1) a polynucleotide molecule comprising a nucleic acid sequence encoding the polypeptide of any one of SEQ ID NOs: 389-582, 883-1032, and 1373-1542, (b1) a polynucleotide molecule comprising the nucleic acid sequence of any one of SEQ ID NOs: 1-194, 583-732, and 1033-1202, (c1) a polynucleotide molecule comprising the nucleic acid sequence of any one of SEQ ID NOs: 195-388, 733-882, and 1203-1372, (d1) a polynucleotide molecule comprising any one of the exonic nucleic acid sequences corresponding to the positions as defined in the Tables 2A-2C, (e1) a polynucleotide molecule comprising a nucleic acid sequence having at least 60%, preferably at least 99% nucleic acid sequence identity to any one of the polynucleotide molecules defined in (a1)-(d1), or (f1) a polynucleotide molecule that hybridizes under medium-high stringency conditions, high stringency conditions, or very high stringency conditions with the full-length complement of any one of the polynucleotide molecules defined in (a1)-(e1);    (3) a vector comprising the polynucleotide molecule;    (4) a recombinant host cell comprising the polynucleotide molecule or the vector;    (5) a composition comprising the polypeptide or the recombinant host cell;    (6) the preparations of the polypeptide; and    (7) use of the polypeptide for the preparation or processing of a food product, for increasing digestion or absorption of animal feed, for the production or processing of kraft pulp or paper, for processing lignin, or for producing ethanol.
