Franciscus J. C. van Gastel has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Phenolic binding peptides
    Patent number: 8293702
    Abstract: The present application relates to peptides which bind to tannin, polyphenolic or anthocyanin compounds, and particularly to tea and wine stains on a fabric or other surface. The invention also concerns binding peptide conjugates which includes a binding peptide coupled to an agent and the use of the binding peptide conjugate for delivering an agent to a desired target.
    Type: Grant

  • Binding Phenol Oxidizing Enzyme-Peptide Complexes
    Publication number: 20080248527
    Abstract: The present application relates to peptides which bind to a target stain, phenol oxidizing enzyme-binding peptide complexes wherein the binding peptide is attached to the C-terminus of the phenol oxidizing enzyme or is inserted or substituted into the phenol oxidizing enzyme. In a preferred embodiment the phenol oxidizing enzyme is a laccase specifically Stachybotrys oxidase B and variants thereof. The invention provides expression vectors comprising the phenol oxidizing enzyme-binding peptide complex as well as host cells comprising the vectors.

  • Method of increasing recovery of heterologous active enzymes produced in plants
    Patent number: 6632930
    Abstract: A method of increasing recovery of active enzyme produced in a plant is provided where the enzyme requires a transitional metal cofactor for activation. The metal cofactor is supplied to the enzyme during plant development, during extraction, or after extraction. Recovery of active enzyme is also provided by incubating the extracted enzyme at a non-enzyme degrading temperature. Addition of a negative ion salt further improves active enzyme recovery. Optimum salt concentrations for recovery of laccase from plants using copper solutions is provided.
