Abstract
The present invention relates to lipase and .alpha.-amylase variants, stabilized towards the inactiviation caused by peroxidase systems, in which variants a naturally occurring tryosine residue has been deleted, substituted with a different amino acid residue at one or more positions. The invention also relates to a method of stabilizing a lipase or an .alpha.-amylase towards the inactivation caused by the preoxidase systems, and detergent compositions comprising a lipase and/or .alpha.-amylase variant of the invention.
