Detergent for Corneum-Derived Stains, and Method for Evaluating Ability to Degrade Corneum-Derived Stains

Abstract

The present invention provides a detergent having a high detergency against corneum-derived stains, a method for evaluating the ability of an enzyme or a composition comprising the enzyme to degrade corneum-derived stains. A detergent comprising an M23A subfamily protease as an active ingredient. A method for evaluating the ability of an enzyme or a composition containing the enzyme to degrade corneum-derived stains, comprising obtaining the degrading activities of the test enzyme or the composition comprising the test enzyme on a reference peptide and one or more substrate peptides and evaluating the ability of the test enzyme or the composition comprising the test enzyme to degrade corneum-derived stains based on the degrading activities of the test enzyme or the composition comprising the test enzyme on the reference peptide and the substrate peptide, wherein the reference peptide is GGGGG or GGGG, the one or more substrate peptides are selected from the group consisting of GGGXG, GXGGG, GGXG, and GXGG, and X is any amino acid residue other than glycine.
