Inteins are protein fragments that allow protein splicing and cyclization by formation of a new peptide bond between the N- and C-termini of the protein. We expected this reporter to result in a higher signal due to the stabilization of the protein by cyclization (Figure 1). To further optimize the dynamic range of the system, a PEST sequence for fast digestion of the protein was included at the C-terminus of the protein. This sequence targets any of the unspliced protein to degradation, while the spliced cyclic protein remains stable, since the PEST sequence is excised along with the intein fragments during the splicing reaction (Kanno2007, Kanno2009). Cyclic luciferase with the SuMMVs sequence (cycLuc_SuMMVs) contains the circularly permutated firefly luciferase, flanked by intein sequences. The two parts of fLuc are connected with the SuMMVps recognition sequence (EEIHLQ-S). Characterization This construct was expressed under CMV promoter and used for testing the orthogonality of different TEVp homologs and studying the activity split SuMMVp measuring the activity of fLuc. The coding sequence for cycLuc_SuMMVs was deposited in pSB1C3. For testing the orthogonality, HEK293T cells were cotransfected by the plasmids with the whole protease and cycLuc reporters as shown on Figure 2. For testing the activity of split proteases, HEK293T cells were cotransfected by the plasmids with rapamycin inducible split protease and corresponding cycLuc reporter as shown on Figure 3. false false _2432_ 29974 29974 9 true - false Katja Leben annotation2514418 1 AU1 range2514418 1 139 156 annotation2514419 1 cLuc range2514419 1 157 1089 annotation2514424 1 PEST range2514424 1 2131 2325 annotation2514422 1 intN range2514422 1 1816 2130 annotation2514417 1 intC range2514417 1 22 138 annotation2514423 1 stop range2514423 1 2326 2328 annotation2514415 1 start range2514415 1 1 3 annotation2514420 1 GS-linker range2514420 1 1090 1125 annotation2514416 1 His-tag range2514416 1 4 21 annotation2514421 1 nLuc range2514421 1 1126 1815 BBa_K1965034_sequence 1 atgcaccaccaccaccaccacatgatcaaaatagccacacgtaaatatttaggcaaacaaaatgtctatgacattggagttgagcgcgaccataattttgcactcaaaaatggcttcatagcttctaattgtttcaatgatacttatagatatattgacaccgctatcctcagcgtggtgccatttcaccacggcttcggcatgttcaccacgctgggctacttgatctgcggctttcgggtcgtgctcatgtaccgcttcgaggaggagctattcttgcgcagcttgcaagactataagattcaatctgccctgctggtgcccacactatttagcttcttcgctaagagcactctcatcgacaagtacgacctaagcaacttgcacgagatcgccagcggcggggcgccgctcagcaaggaggtaggtgaggccgtggccaaacgcttccacctaccaggcatccgccagggctacggcctgacagaaacaaccagcgccattctgatcacccccgaaggggacgacaagcctggcgcagtaggcaaggtggtgcccttcttcgaggctaaggtggtggacttggacaccggtaagacactgggtgtgaaccagcgcggcgagctgtgcgtccgtggccccatgatcatgagcggctacgttaacaaccccgaggctacaaacgctctcatcgacaaggacggctggctgcacagcggcgacatcgcctactgggacgaggacgagcacttcttcatcgtggaccggctgaagagcctgatcaaatacaagggctaccaggtagccccagccgaactggagagcatcctgctgcaacaccccaacatcttcgacgccggggtcgccggcctgcccgacgacgatgccggcgagctgcccgccgcagtcgtcgtgctggaacacggtaaaaccatgaccgagaaggagatcgtggactatgtggccagccaggttacaaccgccaagaagctgcgcggtggtgttgtgttcgtggacgaggtgcctaaaggactgaccggcaagttggacgcccgcaagatccgcgagattctcattaaggccaagaagggatccgaggaaatacacctgcaaagcggctcaggtggccaaaaacattaagaagggcccagcgccattctacccactcgaagacgggaccgccggcgagcagctgcacaaagccatgaagcgctacgccctggtgcccggcaccatcgcctttaccgacgcacatatcgaggtggacattacctacgccgagtacttcgagatgagcgttcggctggcagaagctatgaagcgctatgggctgaatacaaaccatcggatcgtggtgtgcagcgagaatagcttgcagttcttcatgcccgtgttgggtgccctgttcatcggtgtggctgtggccccagctaacgacatctacaacgagcgcgagctgctgaacagcatgggcatcagccagcccaccgtcgtattcgtgagcaagaaagggctgcaaaagatcctcaacgtgcaaaagaagctaccgatcatacaaaagatcatcatcatggatagcaagaccgactaccagggcttccaaagcatgtacaccttcgtgacttcccatttgccacccggcttcaacgagtacgacttcgtgcccgagagcttcgaccgggacaaaaccatcgccctgatcatgaacagtagtggcagtaccggattgcccaagggcgtagccctaccgcaccgcaccgcttgtgtccgattcagtcatgcccgcgaccccatcttcggcaaccagatcatccccgccgagtactgtttaagctatgaaacggaaatattgacagtagaatatggattattaccgattggtaaaattgtagaaaagcgcatcgaatgtactgtttatagcgttgataataatggaaatatttatacacaacctgtagcacaatggcacgatcgcggagaacaagaggtgtttgagtattgtttggaagatggttcattgattcgggcaacaaaagaccataagtttatgactgttgatggtcaaatgttgccaattgatgaaatatttgaacgtgaattggatttgatgcgggttgataatttgccgaacggcggcaagatcgccgtcaattctgcttgcaagaactggttcagtagcttaagccactttgtgatccaccttaacagccacggcttccctcccgaggtggaggagcaggccgccggcaccctgcccatgagctgcgcccaggagagcggcatggatagacaccctgctgcttgcgccagcgccaggatcaacgtctaa igem2sbol 1 iGEM to SBOL conversion Conversion of the iGEM parts registry to SBOL2.1 James Alastair McLaughlin Chris J.
