thiophenols has been developed. Such a probe was designed by using a coelenterazine analogue as the luminophore and dinitrophenyl ether as the recognition moiety. It should be noted that this probe displayed good sensitivity and selectivity toward thiophenols, and has been effectively applied for the quantitative detection of thiophenols in aqueousmedia and complex biological samples.

A bioluminescent protein is provided that includes a substituted luciferase polypeptide having amino acid substitutions at positions 21 and 166, and with one or more additional amino acid substitutions at positions 3, 16, 20, 29, 30, 71, 87, 114, and 144, compared to the parent polypeptide. Also provided is a luciferin that has a selenium-containing group at position C8 of an imidazopyrazine backbone, and methods of making the luciferin. In addition, nucleic acids encoding the bioluminescent protein, cells expressing the bioluminescent protein, and reactions between the bioluminescent protein and luciferin substrates are also provided. Fusions between the substituted luciferase polypeptide and a fluorescent protein are also provided for bioluminescence resonance energy transfer based reporters.
