Design Notes
Synthesis of this part requires it to be broken into three fragments, as there is too much repetition between the three coding regions for them to be synthesized as one gBlock. The anchor binder sequence is flanked by a BamHI cut site, the dimer binder sequence is preceded by a BamHI cut site and flanked by a BglII cut site, followed by the biobrick suffix sequence. The FKPA sequence is preceded by a BglII cut site and flanked by the biobrick suffix sequence. This design allows the user to synthesize all three fragments and build either the part described here, or another part our team submitted that does not contain the FKPA sequence. It is also important to note that for DNA synthesis, the FKPA sequence must be preceded and flanked by terminal adapters; our team had multiple synthesis failures without these adapters. The 5' end adapter is 5'CTCACTTGTAGAACGGTGATCAGCCTGTGCTCTAGAGCCTGATAGTTGAGCGATACACAC3'; the 3' end adapter is 5'acatctatggatgtactcagcgagcagatgctctc3'.
Source
This part came from a synthetic library of nanobodies. The library was created from trinucleotide mutagenesis (TRIM) on the nanobodies naturally found in camels. These nanobodies all share a common scaffold, and have variable regions that allow for a variety of binding. After an extensive screening process this nanobody was chosen because of its binding specificity to CBD. The luciferase coding sequence was identified from Oplophorus gracilirostris, a deep sea shrimp. The FKPA sequence was identified from the E. coli strain MC4100.
