Method for modifying characteristics of a lipase

A method for modifying the stability, activity, or wash performance of a parent lipase, comprising non-covalently associating a peptide to the parent lipase to produce a modified lipase;

• where the parent lipase has at least 90% sequence identity with amino acids 1 to 269 of SEQ ID NO:
• 2;
• where the peptide has at least 90% sequence identity with the amino acid sequence of at least one major lipase contact zone of the propeptide of the parent lipase;
• and
• where the major lipase contact zone of the propeptide corresponds to any of amino acids −57 to −50;
• −40 to −28;
• and −22 to −15 of SEQ ID NO:
• 2,
• wherein the modified lipase has increased thermostability in a detergent as compared to the parent lipase, has decreased lipid stain removal activity as compared to the parent lipase, and/or has increased lipid stain removal activity after contact with a detergent or a protease as compared to the parent lipase.
