Description

field of invention

[0001] The present invention relates to variants of TY145 subtilase and BPN' subtilase and methods of constructing these variants with altered properties, such as stability (e.g. thermostability or storage stability), Ca 2+ dependent, pH dependent activity. Background of the invention

[0002] Enzymes have been used in the detergent industry for over 30 years as part of washing formulations. Proteases are the most relevant enzymes in these preparations from a commercial point of view, but other enzymes including lipases, amylases, cellulases, hemicellulases or enzyme mixtures are also frequently used.

[0003] To improve the cost and / or performance of proteases, proteases with altered properties are being sought such as: higher low temperature activity, higher thermostability, higher specific activity at a given pH, altered Ca 2+ dependence, greater stability in the presence of other detergent ingredients (eg bleach, surfactants, etc.).
