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.

Disclosed herein are compositions and methods to treat hair with a peracid-based benefit agent. The peracid benefit agent can be used for hair bleaching, hair weakening, hair removal, hair waiving, hair straightening or any combination thereof. The peracid may be enzymatically generated from a carboxylic acid ester substrate using an enzyme having perhydrolytic activity (perhydrolase) in the presence of a source of peroxygen. A fusion protein comprising the perhydrolase coupled to a hair-binding domain, either directly or through an optional linker, may be used to target the perhydrolytic activity to the hair surface.

Oral care compositions, oral care systems, oral surface-binding peptides, and a method for applying particles to an oral surface are provided. The oral care system comprises at least one peptidic component comprising a first binding element having affinity for an oral surface and a second binding element having affinity for a ligand property of a particle.

Disclosed herein are compositions and methods to treat an oral cavity surface with a peracid-based benefit agent. The peracid benefit agent can be use for oral surface bleaching, whitening, disinfecting, destaining, deodorizing, decreasing or removing biofilm, and combinations thereof. The peracid is enzymatically generated from a carboxylic acid ester substrate using a CE-7 carbohydrate esterase having perhydrolytic activity (perhydrolase) in the presence of a source of peroxygen. A fusion protein comprising the perhydrolase coupled to a peptidic component having affinity for an oral cavity surface, either directly or through an optional linker, may be used to target the perhydrolytic activity to the oral cavity surface.

摘要:
Peptide tags, referred to here as inclusion body tags, are disclosed useful for the generation of insoluble fusion peptides. The fusion peptides comprise at least one inclusion body tag operably linked to a peptide of interest. Expression of the fusion peptide in a host cell results in a product that is insoluble and contained within inclusion bodies in the cell and/or cell lysate. The inclusion bodies may then be purified and the protein of interest may be isolated after cleavage from the inclusion body tag.
摘要:
Compositions and methods are provided using fusion peptides comprising at least one multi-functional solubility tag having an effective number of cross-linkable cysteines residues. The multi-functional peptidic solubility tags facilitate efficient fusion peptide production, easier downstream processing of the fusion peptide, and provide functional surface properties when coupled to a target material while the cross-linkable cysteines provide enhanced durability when binding the fusion peptide to a target material.
