RBS (Elowitz 1999) -- defines RBS efficiency
Varies from -6 to +1 region from original sequence to accomodate BioBricks suffix. No secondary structures are formed in the given RBS region. Users should check for secondary structures induced in the RBS by upstream and downstream elements in the +50 to -50 region, as such structures will greatly affect the strength of the RBS.

Created from oligos ordered from SigmaAldrich. Oligo sequences: Ptac+ AATTCGCGGCCGCTTCTAGAGGAGCTGTTGACAATTAATCATCGGCTCGTATAATGTGTGGAATTGTGAGCGGATAACAATTTA Ptac- CTAGTAAATTGTTATCCGCTCACAATTCCACACATTATACGAGCCGATGATTAATTGTCAACAGCTCCTCTAGAAGCGGCCGCG
The Ptac promoter is a functional hybrid promoter, derived from the trp and lac promoters, that are regulated by trp and lac [1]. This part also exist together with lacI, part BBa_K180000 [1] Proc. Natl. Acad. Sci. USA, Vol. 80, pp. 21-25
Oligos ordered from SigmaAldrich were annealed to form a double stranded DNA segment, ready to be ligated into any BioBrick backbone.
This is a copy of the Part:B0014. Only here the part is cloned in the standard vector pSB1C3 instead of the pSB1AK3.
Double terminator consisting of BBa_B0012 and BBa_B0011
Derived from luxICDABEG operon terminator of Vibrio fischeri <genbank>AF170104</genbank>.
Bidirectional transcriptional terminator consisting of a 22 bp stem-loop.
In the naturally-occuring sequence there is a mismatch in the stem of the stem loop. This can be corrected via an A->G mutation (at position 40 -- sequence coordinate/not MFOLD coordinate). The above sequence does not reflect this mutation (but the MFOLD image does). This terminator's location cannot be found using some inverted repeat detectors like PALINDROME because it is too short and contains a mismatch. This one was found with the help of Tom Knight. It lies between two coding regions that point towards eachother.
Derived from the TE terminator of T7 bacteriophage between Genes 1.3 and 1.4 <genbank>V01146</genbank>.
Transcription terminator for the E.coli RNA polymerase.
Suggested by Sri Kosuri and Drew Endy as a high efficiency terminator. The 5' end cutoff was placed immediately after the TAA stop codon and the 3' end cutoff was placed just prior to the RBS of Gene 1.4 (before AAGGAG). Use anywhere transcription should be stopped when the gene of interest is upstream of this terminator.
