    • The present invention provides perhydrolase enzyme CD4+ T-cell epitopes, as well as variants that exhibit reduced immunogenic responses, as compared to the parental perhydrolase . The present invention further provides DNA molecules that encode perhydrolase variants, and host cells comprising DNA encoding perhydrolase variants, as well as methods for making perhydrolase enzymes less immunogenic. In addition, the present invention provides variou compositions that comprise perhydrolase variants that are less immunogenic than the wild- type perhydrolase. In some specific embodiments, the present invention provides perhydrolase variants with reduced immunogenicity identified and/or characterized using the methods of the present invention. These enzymes find use in cleaning and other applications. In some preferred embodiments, the present invention finds particular use in applications involving cleaning, bleaching and disinfecting.
    • 与亲本过氧化氢酶相比,本发明提供了过水解酶酶CD4 + T细胞表位,以及表现出降低的免疫原性应答的变体。 本发明还提供了编码过水解酶变体的DNA分子和包含编码过水解酶变体的DNA的宿主细胞,以及制备过水解酶较少免疫原性的方法。 此外,本发明提供了包含与野生型过水解酶相比较少免疫原性的过水解酶变体的变种组合物。 在一些具体实施方案中,本发明提供使用本发明的方法鉴定和/或表征的具有降低的免疫原性的过水解酶变体。 这些酶可用于清洁和其他应用。 在一些优选实施方案中,本发明特别用于涉及清洁,漂白和消毒的应用。
