    摘要: The present invention relates to lipase and .alpha.-amylase variants, stabilized towards the inactiviation caused by peroxidase systems, in which variants a naturally occurring tryosine residue has been deleted, substituted with a different amino acid residue at one or more positions. The invention also relates to a method of stabilizing a lipase or an .alpha.-amylase towards the inactivation caused by the preoxidase systems, and detergent compositions comprising a lipase and/or .alpha.-amylase variant of the invention.

    摘要: Methods for producing polypeptide with altered immunogenicity or improved stability properties are disclosed. The methods involve a) expressing a diversified population of nucleotide sequences encoding a polypeptide of interest, b) screening the polypeptides expressed in step a) for function, immunogenicity and/or stability, c) selecting functional polypeptides having altered immunogenicity and/or increased stability, e.g. functional in vivo half-life as compared to the polypeptide of interest, and d) optionally subjecting the nucleotide sequence encoding the polypeptide selected in step c) to one or more repeated cycles of steps a)-c). In a further step the expressed polypeptides of step a) or c) can be conjugated to at least one non-polypeptide moiety.
