red-shifted coelenterazine derivatives. In this paper, we have described an oxygen-containing coelenterazine derivative with a significant red-shifted (63 nm) bioluminescence signal maximum relative to coelenterazine 400a (DeepBlueC™, 1 ). In cell imaging, the sulfur-containing coelenterazine derivative displayed a significantly (1.77 ± 0.09; P ≤ 0.01) higher luminescence signal compared to coelenterazine

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.
