Abstract
Disclosed herein are compositions and methods to target enzymatic peracid production to a target surface. The peracid benefit agent produced by the targeted perhydrolytic enzyme can be use for a variety of applications such as bleaching, whitening, disinfecting, destaining, deodorizing, and combinations thereof. Specifically, a fusion protein comprising a perhydrolytic enzyme and at least one peptidic component having affinity for a target surface (excluding body surfaces and oral care surfaces) is used in combination with a suitable substrate and a source of peroxygen to enzymatically produce a peracid on or near the surface of the target material. In a preferred aspect, the target surface is a cellulosic material.
