    摘要： The present invention relates to a 35 kDa enzyme exhibiting aminopeptidase activity which is derived from a fungal microorganism, a DNA construct comprising a DNA sequence encoding said enzyme, a recombinant expression vector comprising said DNA construct, and a cell comprising said DNA sequence. The present invention also provides a method for producing said enzyme exhibiting aminopeptidase activity, and an enzyme preparation comprising said enzyme, a bread-improving or dough-improving composition comprising the aminopeptidase of the invention. Finally the invention relates to the use of said enzyme exhibiting aminopeptidase activity or enzyme preparations or compositions thereof.

    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.
