pSB1C3 yGG promoter acceptor vector

The original pSB1C3 backbone has been adapted so that yeast Golden Gate (yGG) promoter parts, conforming to RFC88, can be quickly converted into BioBrick parts that are compatible with the BioBrick assembly standard.

Between the BioBrick prefix and suffix we have introduced two recognition sequences for the type IIS restriction enzyme BsaI. The BsaI sites flank an RFP gene and are oriented to eliminate themselves and the RFP during digestion and ligation of a yGG promoter part. The 4 base pair sticky ends generated by BsaI digestion of the modified pSB1C3 vector are complementary to the 4 base pair overhangs in our Yeast Golden Gate promoter parts, thus enabling yGG to BioBrick promoter part conversion.

The best way to use this part is to perform a simultaneous digestion-ligation reaction, whereby the yGG promoter construct, the modified pSB1C3 vector, BsaI, and ligase are all introduced into a single tube. Selection on chloramphenicol plates will eliminate the background of cells transformed with the original yGG promoter construct entirely. Newly assembled constructs, in which the yGG promoter part has been converted into a BioBrick part, will make white colonies compared to the red colonies produced by intact, RFP-containing pSB1C3 vector.

Sequencing

ProAV sequencing.png

The vector was sequenced from the prefix, across its RFP biobrick and till the suffix. This was done to prove that the prefix and suffix remained the same after ligation of a part through the Golden Gate method.
