    摘要: A biosensor molecule comprises: a protease amino acid sequence; at least one sensor comprising at least one sensor amino acid sequence which is responsive to at least one target molecule; and an inhibitor of the protease activity of said protease amino acid sequence; wherein the biosensor is switchable from a protease active to a protease inactive state, or from a protease inactive to a protease active state when said sensor responds to said target molecule. The biosensor protease may be a protease of a virus such as a Potyvirus or a Flavivirus wherein the inhibitor is an autoinhibitory peptide derived from the virus. The biosensor may respond to the target molecule allosterically or may be cleaved by a target protease molecule.

    摘要: The invention encompasses nucleic acid molecules containing transcription units which encode the flavivirus M and E protein antigens. The flaviviruses include Japanese encephalitis virus, dengue, yellow fever virus and St. Louis encephalitis virus. The nucleic acids function to provide the M and E protein antigens when the nucleic acid resides in an appropriate host cell, especially when the host cell is the cell of a subject. The invention also encompasses a vaccine whose active agent is the nucleic acid. The invention further encompasses the cultured host cells when they contain within them nucleic acid molecules containing the transcription units. The invention in addition encompasses a method of immunizing a subject against flavivirus infection by administering to the subject an effective amount of a vaccine containing a nucleic acid molecule containing the transcription unit of the invention.
