Procedure1. Amplify 8 biobricks and 3 backbonesPlasmid 1: Already assembledPlasmid 2:2. (VioA-E) I712074 + K274002 pSB3T5Plasmid 3:3. Make ptrpL biobrick (K360023)4. (Attach RBS) B0034 + C0052 [CI434R]5. (cI434) K360023 + CI434R pSB2K3 Plasmid 4:6. (Attach RBS) B0034 + C0051 [CIR]7. (pRM + T7) I12040 + I712069 [RT7]8. (RT7 + cI) [RT7] + CIR pSB4A5Finalize:9. Transform with A C K T

Plasmid Backbones• pSB3T5—Plate 1—7C, 3252bp– Medium copy-p15A– Tetracyline resistance

• pSB2K3—Plate 1—5C, 4425bp– Low copy-F’/P1, High copy inducible with IPTG– Kanamycin resistance

• pSB4A5—Plate 1—1I, 3395bp– Low copy-pSC101– Ampicillin resistance

agttaactagtacgcaagttcacgTGCTAGCAGCGGCCGCTGCAGGAAGAAAC– 108bp– Uppercase letters are modified biobrick prefix/suffix– Bold is trpR binding site (CTAG sequences in particular)– Underlined are SpeI restriction sites which kill RFC10

• Switch SpeI to NheI in biobrick suffix (NheI can still ligate to XbaI)• Idea from UNAM 2010

• Ligate into linearized backbone pSB1C3 (2070bp)– EcoRI + PstI– Transform onto chloramphenicol plates

• Submit to library (need special permission)

lovTAP• Activated by 470nm light• When active, acts as trpR– Represses ptrpL

• Stays active for about 1 minute
