Coding sequences for spaIFEG cluster. Device uses Pveg/spoVG promoter/RBS (BBa_K143053) and double terminator (BBa_B0014). This device will confer immunity to subtilin lantibiotic.
SpaI uses spoVG RBS (BBa_K143021), spaFEG uses native RBS (spaF and spaE RBS are in the coding sequence of preceding protein coding sequence). SpaG has had its TAG stop codon replaced with TAATAA.

Promoter veg a constitutive promoter for B. subtilis
The Pveg promoter was suggested to us by Dr. Jan-Willem Veening of Newcastle University. This sequence supplied was compared to that of the DBTBS database#3 then a section containing the binding site synthesised by Geneart.
Pveg is a constitutive promoter that constitutively expresses the P43 protein in ''B.subtilis''. Pveg contains binding sites for the ''B.sutbilis'' major sigma factor#1. Pveg in ''B.subtilis'' utilises two binding sites to cause high expression of genes#2, however our Pveg is lacking the upstream site to give a medium level of gene expression. It has been noted that the sporulation master regulatoion factor spoOA interacts with Pveg though it is not known how#3. The context with which we used the promoter Pveg is as a '''Polymerase Per Second''' (PoPS) generator.
The biobrick part was designed to include a single binding site for the ''B.subtilis major sigma factor. In addition the biobrick standard was applied to the promoter Pveg sequence.
Coding sequences and RBS' for spaIFEG cluster.

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.

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.
