Abstract: This invention relates to a method for screening libraries of enzyme variants for changes in specific activity by expression of a fusion protein consisting of at least two enzymes. By using one enzyme as a marker changes in specific activity for the other enzyme can be screened efficiently.

Abstract: The present invention relates to polypeptides having glucoamylase activity and isolated polynucleotides encoding said polypeptides. The invention also relates to nucleic acid constructs, vectors, and host cells comprising the polynucleotides as well as methods for producing and using the polypeptides. The invention also relates to the composition comprising a glucoamylase of the invention as well as the use such compositions for starch conversion processes, brewing, including processes for producing fermentation products or syrups.

Abstract: The present invention relates to polypeptides comprising a carbohydrate-binding module amino acid sequence and,an alpha-amylase amino acid sequence as well as to the application of such polypeptides.

Abstract: Variants of fungal cutinases having improved thermostability comprise substitution of one or more specified amino acid residues and/or a specified N-terminal extension. The variants may optionally comprise additional alterations at other positions.

Abstract: The present invention relates to nucleic acids encoding polypeptides having glucanotrans-ferase activity, nucleic acid constructs, recombinant expression vectors, recombinant host cells and methods for producing polypeptides having glucanotransferase activity.

Abstract: The present invention relates to cutinase variants having improved thermostability. The variants have one or more amino acid substitutions within the vicinity of the N-terminal amino acid.

Abstract: The present invention relates to phytase variants derived from a parent phytase which is homologous to a Peniophora lycii phytase and comprises at least one substitution in at least one of a number of positions corresponding to a position in the Peniophora lycii phytase. The variants are of improved properties, in particular of a higher specific activity and/or more thermostable than the parent phytase, e.g. of a Tm of up to 82° C. at pH 5.5, as determined by DSC, and/or of a doubled specific activity. The invention also relates to DNA encoding the phytase variants, methods of their production, as well as the use thereof, e.g. in animal feed and animal feed additives.

Abstract: The present invention relates to isolated polypeptides having glucanotransferase activity and isolated nucleic acid sequences encoding the polypeptides. The invention also relates to nucleic acid constructs, vectors, and host cells comprising the nucleic acid sequences as well as methods for producing and using the polypeptides.

Abstract: Variants of fungal cutinases having improved thermostability comprise substitution of one or more specified amino acid residues and/or a specified N-terminal extension. The variants may optionally comprise additional alterations at other positions.

Abstract: The invention provides variant lipases with improved washing performance, including good performance in washing with a detergent having a high content of anionic surfactant at low washing temperature at a short washing time. More particularly, the invention relates to variants of the wild-type lipase from Pseudomonas sp. strain SD 705, deposited as FERM BP-4772.

Abstract: The present invention provides a protease obtained from Bacillus, which is enzymatically active at alkaline pH and high temperature in the presence of surfactants. In a preferred embodiment, the protease is isolated from Bacillus sp. SD 114 and has a molecular weight of about 29,000 and a pI of about 10.
