Cloning Strategy

As we plan to generate several fusion proteins with different linkers, we decided to use the cloning strategy BBF RFC28: A method for combinatorial multi-part assembly based on the Type IIs restriction enzyme AarI (http://dspace.mit.edu/handle/1721.1/46721). The advantage of this strategy is that we can clone up to 3 different inserts into one vector simultaneously in a 96 well format.

generation of BioBricks

All utilized parts will be generated by PCR and subcloned into the storage vector pSEVA132 (Victor de Lorenzo's lab, KanR, BBR1 ori) allowing blue white screening. The working process for the generation of the subparts is as follows:
1. Ordering of primers (if template is available)
2. PCR
3. clean-up of PCR product
4. Ligation into storage vector
5. Transformation
6. Blue-white screening
7. Sequencing

Due to the presence of rare codons in the sequence of PhyB and Pif3, these two genes will be ordered from GenArt. However, as synthesizing takes several weeks, expression of the wild-type gene of these two proteins will be tested and if satisfying proceeded with these constructs.
