Abstract
The invention relates to novel variants of the enzymatic peptide pullulanase, the gene sequences encoding said novel peptides, expression vectors comprising those gene sequences as well as organisms expressing the novel pullulanase variants. The novel pullulanase variants of the present invention were made empirically by the use of codon-optimization procedures, selective truncation of “wild-type” molecules and through the replacement of selected amino acid residues. Furthermore, the invention relates to the use of these novel pullulanase peptides in the textile, fermentation, food and other industries.
