  • Publication number: 20220154226
    Abstract: The present invention relates to a variant pullulanase, having increased thermo-stability and/or increased thermo-activity compared to a parent pullulanase, comprising a substitution at least a one position selected from a position corresponding to positions 432, 486, 370, 17, 77, 103, 106, 107, 190, 196, 197, 262, 279, 283, 321, 367, 375, 382, 399, 401, 402, 411, 412, 434, 435, 443, 446, 459, 460, 479, 490, 498, 514, 529, 531, 533, 541, 545, 581, 583, 595, 649, 665, 688, 700, 709, 804, 811 of SEQ ID NO: 1, and optionally a deletion of one or more, e.g., all amino acids at positions 821, 822, 823, 824, 825, 826, 827, and 828, wherein the variant has pullulanase activity, and wherein the variant has at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, at least 96%, at least 97%, at least 98%, or at least 99%, but less than 100% sequence identity to a parent alpha amylase selected from the group consisting of SEQ ID NO: 1, SEQ ID NO: 3, SEQ ID NO: 4, SEQ ID NO: 5.

  • Publication number: 20220090041
    Abstract: The present invention relates to protease variants, having improved properties compared to the parent protease, in particular variants of a serine protease belonging to family 53 derived from a strain of Meripilus giganteus. The variants according to the invention have in particular increased thermo-stability, e.g., increased residual activity after 30 min at a temperature in the range from 55 to 60° C. and/or increased thermal denaturation temperature, compared to the parent Meripilus giganteus protease. The present invention also relates to polynucleotides encoding the variants; nucleic acid constructs, vectors, and host cells comprising the polynucleotides; and methods of using the variants.
