The invention relates to novel alkaline protease variants. These variants have, when enumerating the alkaline protease from, variations in amino acid position 61, positions 199 and/or 211 and, optionally, at least one modification that contributes to the stabilization of the molecule, said modification preferably being point mutations in positions 3 and/or 4. Particularly preferred are variants S3T/V41/G61A/V199] and S3T/V41/G61A/V1991/L211D ofalkaline protease. The invention also relates to the possible use of these enzymes in diverse technical processes and, in particular, to detergents and cleansers containing these novel alkaline protease variants.
