Abstract
The present invention provides methods for protein engineering and serine protease variants produced there from. Specifically, the present invention provides serine protease variants having one or more substitutions as compared to a reference serine protease. In addition, the present invention provides compositions comprising these serine protease variants. In some embodiments, the present invention provides cleaning compositions comprising at least one of these serine protease variants.
