Subtilase enzymes of the I-S1 and I-S2 sub-group having an additional amino acid residue in an active site loop region

Subtilase enzymes of the I-S1 and I-S2 sub-groups having an additional amino acid residue in position 96 of the active site loop (b) region from position 95 to 103. Variant subtilases exhibit improved wash performance in a detergent in comparison to its parent enzyme.
