This part was created by standard assembly from construction intermediates: I746911 was put together with I746916:B0015
This is one of the constructs used to characterise superfolder GFP (see I746916 part description for source and other information about this GFP variant)
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.

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.
Transcriptional terminator consisting of a 64 bp stem-loop.
T7 RNA polymerase with RBS (ribosome-binding site) and NLS (nuclear localisation signal). NLS is used to target the protein to the cell nucleus.
DNA was isolated from BL21 and PCR was performed to attach RBS and NLS.
This is the promoter for the ''Eschaerichia coli'' JM109 ''cstA'' gene. It includes the CRP-binding site and the RNA polymerase-binding site. Low glucose concentration results in increased activity by adenylate cyclase. cAMP binds to the cAMP receptor protein, which, in its bound form, is able to associate with the promoter and promote transcription of the downstream gene. (''cstA'' encodes the carbon starvation protein.)
Superfolder GFP was originally described by: Pedelacq et al (2006): "Engineering and characterization of a superfolder green fluorescent protein", Nature Biotech 24 (1) January 2006 This version was synthesised de novo (by Geneart).
This is the coding sequence of superfolder GFP (Pedelacq et al (2006): "Engineering and characterization of a superfolder green fluorescent protein", Nature Biotech 24 (1) January 2006). It carries the following amino acid changes with respect to mut3 GFP (E0040), the currently most commonly used GFP in the registry: S30R, Y39N, F64L, G65T, F99S, N105T, Y145F, M153T, V163A, I171V, A206V Its in-vivo properties are considerably improved with respect to mut3 - it develops fluorescence about 3fold faster than mut3 GFP and reaches 4fold higher absolute fluorescence levels. Fluorescenct colonies can be identified with the naked eye even without UV or blue light illumination (that is to say the amount of blue light in normal daylight or lablight is sufficient). Additionally it is more stable in vitro and refolds faster after in vitro denaturation with respect to mut3 GFP. Note: Superfolder GFP is available in constructs driven by the pBAD and T7 promoters: part numbers I746908 and I746909 respectively. Additionally 6-his tagged versions for protein purification exist: I746914 (pBAD driven) and I746915 (T7 driven).
Codon optimisation before de novo synthesis was carried out for both, E.coli and Bacillus subtilis.
