  • Subtilase Vairants
    Publication number: 20140073552
    Abstract: The present invention relates to enzymes produced by mutating the genes for a number of subtilases and expressing the mutated genes in suitable hosts are presented. The enzymes exhibit improved stability and/or improved wash performance in any detergent in comparison to their wild type parent enzymes. The enzymes are well-suited for use in any detergent and for some in especially liquid or solid shaped detergent compositions.
