Part:BBa_K592000

cph8 (Cph1/EnvZ fusion)

This part is a red-light induced sensor, identical to BBa_I15010, and requires PCB chromophore synthesis by the BBa_I15008 and BBa_I15009 genes. The maximal response is located around the wavelength 650 nm.

We were unable to transform BBa_I15010 from the the 2011 iGEM distribution kit. PCR attempts using VF2 and VR failed to amplify any DNA from the well sample. In the end, we chose to amplify cph8 from Jeffrey Tabor's pJT122 plasmid provided by Chris Voigt. The cph8 in pJT122 contained an internal PstI site, which was removed by point-mutagenesis. The resultant DNA sequence is identical to that of BBa_I15010.
