    • The present invention is related to a fungal serine protease enzyme, which said enzyme has serine protease activity and comprises an amino acid sequence of Malbranchea ALKO4122 mature protease as defined in SEQ ID NO:18 or an amino acid sequence having at least 66% identity to the amino acid sequence of SEQ ID NO:18. Also disclosed is an isolated nucleic acid molecule, comprising a polynucleotide sequence which encodes a fungal serine protease enzyme, nucleic acid sequences encoding said protease, a host cell and a process of producing a polypeptide having serine protease activity. Said protease is useful as an enzyme preparation applicable in detergent compositions and for treating fibers, wool, hair, leather, or silk, for treating food or feed, or for any applications involving modification, degradation or removal of proteinaceous material.
    • 本发明涉及真菌丝氨酸蛋白酶,所述酶具有丝氨酸蛋白酶活性并且包含如SEQ ID NO:18中定义的畸枝霉属ALKO4122成熟蛋白酶的氨基酸序列或氨基酸序列 序列与SEQ ID NO:18的氨基酸序列具有至少66%的同一性。 还公开了分离的核酸分子,其包含编码真菌丝氨酸蛋白酶的多核苷酸序列,编码所述蛋白酶的核酸序列,宿主细胞和产生具有丝氨酸蛋白酶活性的多肽的过程。 所述蛋白酶可用作可用于洗涤剂组合物中并用于处理纤维,羊毛,毛发,皮革或丝的酶制剂,用于处理食物或饲料,或用于涉及蛋白质物质的改性,降解或除去的任何应用。

    • The present invention relates to fungal serine protease variants, which comprise an amino acid substitution of valine at position 208 of the parent Fusarium equiseti Fe_RF6318 serine protease, wherein the position of the substitution corresponds to the amino acid sequence of the mature Fe_RF6318 enzyme defined in SEQ ID NO: 2. The variants have improved thermal stability and/or detergent stability compared to the parent Fe_RF6318 enzyme. Preferably the substitution is V208I and more preferably the variants comprise additional amino acid changes which further increase the stability. Also disclosed are nucleic acid sequences encoding said protease variants as well as recombinant vectors and host cells for the production of the variants. The serine protease variants are applicable in laundry and dish-washing detergent compositions, in treating fibers, in treating wool, in treating hair, in treating leather, in treating food or feed, or in any application involving modification, degradation or removal of proteinaceous material.
    • 本发明涉及真菌丝氨酸蛋白酶变体,其包含母本镰刀菌属Fe_RF6318丝氨酸蛋白酶的208位的缬氨酸的氨基酸取代,其中取代的位置对应于SEQ ID NO:1中定义的成熟Fe_RF6318酶的氨基酸序列 所述变体与母体Fe_RF6318酶相比具有改善的热稳定性和/或洗涤剂稳定性。 优选地,取代是V208I,更优选地,变体包含进一步增加稳定性的另外的氨基酸变化。 还公开了编码所述蛋白酶变体的核酸序列以及用于产生变体的重组载体和宿主细胞。 丝氨酸蛋白酶变体可用于洗衣和洗碟洗涤剂组合物,处理纤维,处理羊毛,处理毛发,处理皮革,处理食品或饲料,或涉及任何涉及蛋白质物质的改性,降解或去除的应用 。
