Module III - Isobutanol production
Alcohol dehydrogenase (AdhA)
We found out, that the AdhA from L. Lactis is the best alcoholdehydrogenase in literature (Atsumi et al., 2010). For that reason we want to increase the production of isobutanol by putting the adhA gene behind our producing pathway. The adhA from L. Lactis was not available as a BioBrick so we designed a new part which contains the coding sequence of the adhA gene from L. Lactis (BBa_K1465301). You can find our approach in the following sections.
Cloning
For the isolation of the adhA gene from L. lactis we first had to isolate the DNA of it. Afterwards we tried to amplify the adhA gene with the primer rev_pSB1C3_adhA and fw_adhA_pSB1C3. Together with the amplified backbone we performed a Gibson Assembly. All verifications showed that our cloning was successful but our backbone was pSB1K3 and not pSB1C3. For that reason we performed a successful recloning in pSB1C3 and our part BBa_K1465301 was ready for usage.
