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.

cI repressor from E. coli phage lambda (+LVA)
Elowitz, M. B. Transport, Assembly, and Dynamics in Systems of Interacting Proteins. Thesis, Princeton Univ., Princeton (1999).
Coding region for the cI repressor based on cI repressor from bacteriophage lambda modified with an LVA tail for rapid degradation of the protein. cI repressor binds to the cI regulator (BBa_R0051).

It has been modified to include a rapid degradation LAA tail, and includes the BioBrick standard assembly head and tail restriction sites. The RBS has been removed. The stop codon has been changed from TAA to a double stop codon TAATAA.

**highly** engineered mutant of red fluorescent protein from Discosoma striata (coral)
Campbell et al., PNAS v99 p7877 URL
monomeric RFP: Red Fluorescent Protein. Excitation peak: 584 nm Emission peak: 607 nm
TAATAA double stop codon added (DE). Four silent mutations made to remove three EcoRI sites and one PstI site: A28G, A76G, A349G, G337A.
This device accepts PoPS as input and produces the LuxI enzyme. This enzyme produces 3OC6HSL.
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.
V. fischeri <genbank>AF170104</genbank>
Synthesizes 3OC6HSL, which binds to LuxR. The lux cassette of V. fischeri contains a left and a right promoter. The right promoter gives weak constitutive expression of downstream genes.This expression is up-regulated by the action of the Lux repressor, LuxR. Two molecules of LuxR protein form a complex with two molecules the signalling compound HSL. This complex binds to a palindromic site on the promoter, increasing the rate of transcription.
An LVA tail (sequence: AANDENYALVA) was added to increase protein degradation. .
