Part:BBa_K1616001

partinfo>BBa_K1616001 short</partinfo>
Vivid (VVD) is the smallest known Light–oxygen–voltage (LOV) domain protein and photo-inducible dimer. Isolated from Neurospora crassa, VVD forms a homodimer in response to a blue-light stimulus. Then, a split protein is a protein whose sequence has been divided into two (or more) different parts. The yellow-fluorescent (YFP) protein will only express fluorescence when its two parts will be reunited. The part is coding for the homodimer VVD links by an integration of specific sequence to the C terminal of the YFP split.

So, this part works with BBa_K1616002. In absence of blue-light, the conformation of the VVD photoreceptor will prevent the formation of the complete fluorescent protein while in presence of the light signal the YFP protein will be reconstituted leading to the fast expression of a yellow fluorescence in our bacteria.

Design Notes

The sequence of VVD had 2 illegal sites PstI; that have been removed.

Source

This part have been created thank to gblock, our team have assembled the sequence of photoreceptor VVD (without illegal site), a linker(1) and then the C terminal of YFP split(1).
