Part:BBa_K1616024

VVD and YFP complex

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 N terminal of the YFP split. The downstream part of this composite is double T7 terminator (BBa_B0015).

So, this part works with BBa_K1616001. 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.
