  • Patent number: 8815550
    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.

  • Publication number: 20140221608
    Abstract: An acid-cleavable peptide linker comprising aspartic acid and proline residues is disclosed. The acid-cleavable peptide linker provides an altered sensitivity to acid-hydrolytic release of peptides of interest from fusion peptides of the formula PEP1-L-PEP2. The inventive linker, L, is described in various embodiments, each of which provides substantially more rapid acid-release of peptides of interest than does a single aspartic acid-proline pair. In an additional aspect, a method of increasing the stability of an acid cleavable linkage to acid hydrolysis is also provided.

  • Patent number: 8663616
    Abstract: 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.

  • Patent number: 8617843
    Abstract: The invention relates to the recombinant expression of a peptide of interest in the form of a fusion protein comprising a solubility tag. The fusion protein comprises at least two portions separated by a cleavable peptide sequence wherein one portion is devoid of cysteine residues and the second portion comprises an effective number of cross-linkable cysteine residues. After cell lysis and isolation of the fusion protein, the fusion protein is subsequently cleaved into a mixture of first and second portions. Oxidative cross-linking is used to selectively precipitate one of the two portions to facilitate simple and effective separation of the peptide of interest.

  • Publication number: 20130171217
    Abstract: Disclosed herein are compositions and methods to treat skin with a peracid-based benefit agent. The peracid benefit agent can be used for a benefit such as the prevention or treatment of acne, skin whitening, skin bleaching, skin conditioning, reducing the appearance of skin wrinkles, skin rejuvenation, reducing dermal adhesions, and preventing, reducing or eliminating body odors 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 skin-binding domain, either directly or through an optional linker, may be used to target the perhydrolytic activity to the skin surface.
