| 摘要 |
A chimeric photoprotein (I) obtained by replacing a region of Obelin protein comprised between the first and the second calcium binding sites with a corresponding region of a photoprotein chosen from Clytin, Aequorin, Thalassicolin, Mitocromin, Mnemiopsin and Berovin, is new. Independent claims are also included for the following: (1) a fusion product between (I) and a different (poly)peptide; (2) a conjugation product (II) between (I) and a molecule of analytical, diagnostic or therapeutic interest; (3) an isolated nucleic acid molecule (III) encoding (I), having a sequence chosen from a sequence of 600 or 607 nucleotides fully defined in specification; (4) a host cell (IV) bearing (III); (5) producing (I); and (6) a bioluminescence resonance energy transfer (BRET) system, comprising a fluorescent protein and (I). |
