Patent

CA 2189428

The present invention relates to fabric cleaning compositions comprising subtilisin BPN' variants, wherein the BPN' variant comprises one or more amino acid positions having a different amino acid than that occurring in wild-type subtilisin BPN' (i.e., substitution) at specifically identified positions, whereby the BPN' variant has decreased adsorption to, and increased hydrolysis of, an insoluble substrate as compared to wild-type subtilisin BPN'.

Compositions de lessives pour textiles contenant des variants de subtilisine BPN', lesdits variants de BPN' comprenant une ou plusieurs positions d'acides aminés qui présentent un acide aminé différent de celui présent dans la subtilisine BPN' de type sauvage (par ex. substitution) à des positions spécifiquement identifiées. Lesdits variants de BPN' présentent une adsorption réduite dans un substrat insoluble et une hydrolyse accrue dudit substrat par comparaison à la subtilisine BPN' de type sauvage.
