BBa_K1399008 1 BBa_K1399008 GFP (mut3b) with DAS-ssrA degradation tag 2014-09-18T11:00:00Z 2015-05-08T01:10:16Z GFP comes from part BBa_E0040, the tag sequence was obtained from part BBa_M0052. GFP (mut3b) (see part BBa_E0040) with added DAS-ssrA degradation tag (see part BBa_M0052). The tag increases GFP turn-over rate, thus providing better temporal resolution of green fluorescence. In the same time, maximal fluorescence amplitudes will be lower as newly formed protein is degraded as soon as it is formed. SsrA tags encode peptide sequence that 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 DAS tag encodes peptide sequence AANDENYADAS is reported to have low affinity to ClpX thus its mediated degradation very much depends on the concentration of SspB (ClpX mediator).[1] However, be aware that exact protein degradation rate is influenced by multiple other factors: ClpXP and ClpAP protease concentrations, protein stability, Km of binding to the protease, temperature [3]. ===References=== [1] Flynn, J.

Different parts of the tag are recognized by different proteins, for example, the final 3 residues (DAS in this case) are recognized 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. false Anna Stikane annotation2383928 1 start range2383928 1 1 3 annotation2383930 1 DAS-ssrA tag range2383930 1 715 747 annotation2383931 1 stop range2383931 1 748 750 annotation2383932 1 stop range2383932 1 751 753 annotation2383929 1 GFP (mut3b) range2383929 1 3 714 BBa_B0034 1 BBa_B0034 RBS (Elowitz 1999) -- defines RBS efficiency 2003-01-31T12:00:00Z 2015-08-31T04:07:20Z Released HQ 2013 RBS based on Elowitz repressilator. false true _1_ 0 24 7 In stock false Varies from -6 to +1 region from original sequence to accomodate BioBricks suffix. <p>No secondary structures are formed in the given RBS region.
