The present invention relates to variants (mutants) of polypeptides, in particular Termamyl-like alpha-amylases, which variant has alpha-amylase activity and exhibits an alteration in at least one of the following properties relative to said parent alpha-amylase: substrate specificity, substrate binding, substrate cleavage pattern, thermal stability, pH/activity profile, pH/stability profile, stability towards oxidation, Ca2+ dependency, specific activity, in particular laundry and dish-wash applications.
La présente invention concerne des variants (mutants) de polypeptides, en particulier d'alpha-amylases de type Termamyl, lesdits variants présentant une activité alpha-amylase et présentant une modification au niveau d'au moins l'une des propriétés suivantes relativement auxdites alpha-amylases parentes : spécificité du substrat, liaison au substrat, motif de clivage du substrat, stabilité thermique, profil d'activité/pH, profil de stabilité/pH, stabilité vis-à-vis de l'oxydation, dépendance du Ca2+, activité spécifique, dans des applications de lavage de vaisselle et de blanchisserie particulières.
