Abstract

The present invention is directed to novel spontaneously fluorescent proteins having a unique chromophore formed from the amino acid sequence FR1R2R3F where R1 is Q or S; R2 is Y, W, F or H; and R3 is G, A or S (SEQ ID NO:34). The invention also encompasses the expression of nucleic acids that encode the proteins of the invention in a wide variety of engineered host cells, and the isolation of engineered proteins. In other embodiments, the invention comprises methods of use, generally including tagging a molecule or cell with the proteins of the invention by either chemical means or recombinant techniques.
