NOVELTY - Isolated polypeptide (P1) having glucoamylase activity, comprising: a polypeptide having at least 80% sequence identity to the mature polypeptide of SEQ ID NO: 2 (comprising a fully defined sequence of 568 amino acids as given in the specification); and a fragment of SEQ ID NO: 2 that has glucoamylase activity, is new.    USE - The isolated polypeptide having glucoamylase activity is useful for producing a fermentation product from starch-containing material (claimed), where fermentation product is e.g. alcohols (e.g. ethanol), organic acids (e.g. citric acid), ketones (e.g. acetone), amino acids (e.g. glutamic acid), antibiotics (e.g. penicillin), enzymes, vitamins (e.g. riboflavin) and hormones, fuel ethanol, drinking ethanol, beer and wine, fermented dairy products and beverages.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for:    (1) an isolated polypeptide (P2) comprising a catalytic domain comprising: a catalytic domain having at least 80% sequence identity to amino acids 19-468 of SEQ ID NO: 2; and a fragment of amino acids 19-468 of SEQ ID NO: 2 that has glucoamylase activity;    (2) an isolated polypeptide (P3) comprising a carbohydrate binding domain operably linked to a catalytic domain, where the binding domain is: a carbohydrate binding domain having at least 80% sequence identity to amino acids 475-568 of SEQ ID NO: 2; and a fragment of amino acids 475-568 of SEQ ID NO: 2 that has carbohydrate binding activity;    (3) producing a fermentation product from starch-containing material comprising either: liquefying starch-containing material, saccharifying the liquefied material with the polypeptide (P1), and fermenting with a fermenting organism; or saccharifying starch-containing material with the polypeptide (P1) at a temperature below the initial gelatinization temperature of the starch-containing material, and fermenting with the fermenting organism;    (4) an isolated polynucleotide encoding the polypeptide (P1);    (5) a nucleic acid construct or recombinant expression vector comprising the polynucleotide operably linked to at least one control sequence that directs the production of the polypeptide in an expression host;    (6) a recombinant host cell comprising the polynucleotide operably linked to the control sequences that direct the production of the polypeptide;    (7) producing a polypeptide having glucoamylase activity; and    (8) an isolated polynucleotide encoding a signal peptide comprising of amino acids 1-17 of SEQ ID NO: 2.
