2. A fusion protein comprising
a LuxP moiety, wherein the LuxP moiety is disposed between a donor and acceptor moiety; -
a cyan fluorescent protein donor moiety connected to the LuxP moiety; and a yellow fluorescent protein acceptor moiety connected to the LuxP moiety, wherein the yellow fluorescent protein is adapted to be substantially insensitive to chloride ion concentration, and wherein the donor and acceptor moieties disposed so that they are capable of fluorescent energy transfer when no ligand is bound to the LuxP moiety, and exhibit diminished or no fluorescent energy transfer when ligand bands to LuxP.
