Phillipe Potin 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).

  • Sulfohydrolases, corresponding amino acid and nucleotide sequences, sulfohydrolase preparations, processes, and products thereof
    Publication number: 20040101942
    Abstract: A purified sulfohydrolase having a purity level based on total amount of protein of at least about 40 wt %. Isolated nucleic acid sequence and amino acid sequences. A process for purifying at least one sulfohydrolase, including subjecting an extract from seaweed to fractionation to obtain fractions; and subjecting at least one of the fractions to phenyl sepharose chromatography to obtain sepharose fractions containing at least one sulfohydrolase. An enzymatically modified compound which has been modified by an isolated sulfohydrolase having a purity level based on total amount of protein of at least about 40 wt %. A process of enzymatically modifying a sulfated compound, including combining at least one sulfohydrolase, having a purity level based on total amount of protein of at least about 40 wt %, with a sulfated compound form a reaction mixture; and incubating the reaction mixture to remove sulfate groups from the sulfated compound to form an enzymatically modified compound.
