Inverting regulatory region controlled by LacI (<bb_part>BBa_C0010</bb_part>, <bb_part>BBa_C0011</bb_part>, etc.) <p> The pLac regulatory region is a 243 base-pair sequence with standard BioBrick prefix and suffix sections on its ends. It contains two protein binding sites: CAP, which is generally present in E.coli and is assocciated with cell health and availability of glucose., and LacI, the Lac inhibitor <bb_part>BBa_C0010</bb_part> which binds in an dimerized cooperative manner to inhibit the transcription of the protein that follows. In the presence of lactose or IPTG, an analog of lactose, LacI is unable to correctly bind and inhibit transcription. This allows <bb_part>BBa_R0010</bb_part> to be used as a inverter or as a detector of lactose or IPTG.

Lactose/IPTG inducible promoter with GFP reporter tagged with AAV-ssrA degradation tag followed by terminator.
The tagged GFP is actively degraded within cell, thus provides better temporal resolution of green fluorescence and promoter activity.

GFP (mut3b) with AAV-ssrA degradation tag
2014-09-18T11:00:00Z
2015-05-08T01:10:16Z
GFP comes from part BBa_E0040, tag sequence was obtained from part I11012, but same tag was also used in paper by Andersen et al., (1998).[2]
GFP (mut3b) (see part BBa_E0040) with added AAV-ssrA degradation tag (part BBa_I11012). The tag increases RFP turn-over rate, thus providing better temporal resolution of red fluorescence. In the same time, maximal fluorescence amplitudes will be lower as newly formed protein is degraded as soon as it is formed.
The tag encodes peptide sequence AANDENYAAAV and is recognized by ClpA and ClpX unfoldases and ClpX mediator SspB.[1] ClpA and ClpX then form a proteosome-like complex with ClpP protease and the protein is degraded.[1]
The final three residues of the tag determines the strength of interaction with ClpX and thus the final protein degradation rate.[2] The AAV tag is reported to lead to reasonably fast protein degradation, degrading GFP with rate -0.012 per minute.[2] However, be aware that exact protein degradation rate depends on multiple factors: ClpXP and ClpAP protease and SspB mediator concentrations, protein stability, Km of binding to the protease, temperature [3].

The tag was attached to RFP using PCR and MABEL (mutagenesis with blunt-end ligation), thus avoiding introduction of additonal residues and restriction site. Different parts of the tag are recognized by different proteins, for example, the final 3 residues (AAV in this case) are recognised by ClpX, whereas first 4 residues of the tag are required for efficient SspB binding.[1] Thus modifications of these critical residues alter the efficacy with what different proteases bind to it.

Varies from -6 to +1 region from original sequence to accomodate BioBricks suffix. <p>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.
