- | * '''Team Site Directed Mutagenesis:''' Preparations for plasmid-isolations of ''B.pumi''_2883_IV (I-IV); ''X.camp''_3633 (I-IV); ''X.camp.''_2247_2 (I-IV) and ''B.pumi''_2883_III (I-IV)

- | * '''Team Cellulose Binding Domain:''' Redesigned the primer-sequences another time giving the CBDs a few AS more in than the Protein-BLAST said. CBDcex: 4 AS N-terminal, 2 C-terminal. CBDclos: 2 N-terminal (starting with a natural ATG) and 2 AS C-terminal.

- | **Prepared BBa_392014 for Sequencing
| + | |
- | * '''Team Bacterial Laccases:''' Restriction of Tv5 laccase PCR product with Prefix and Suffix ends for cloning in pSB1C3 and restriction of laccase with the overhangs for cloning in shuttle vector. And we did the PCR on Tv35 with both primer pairs again. This time we lowered the annealing temperatures and got products with both primer pairs.

- | :The ''B.pumilus'' site directed mutation at 2317 is not a illegal restriction site, so it can not be checked via restriction, but only through sequencing.

- | :*Picked a few more Colonies of X.camp for plasmid-isolation
| + | |
- | * '''Team Bacterial Laccases:'''
| + | |
- | :* Ligation of Tv5 laccase with pSB1C3 backbone and purification of Tv35 laccase PCR products.
| + | |
- | :* After our laccases seemed not to get produced we decided to try to express the laccases with constitutive promoters. Therefore we designed primers with the sequences of different promoters from the [Enderson promoter family]. We chose the promoter sequences of the parts [http://partsregistry.org/wiki/index.php/Part:BBa_J23103 BBa_J23103], [http://partsregistry.org/wiki/index.php/Part:BBa_J23103 BBa_J23110] and [http://partsregistry.org/wiki/index.php/Part:BBa_J23103 BBa_J23117] and for all three promoters the RBS [http://partsregistry.org/wiki/index.php/Part:BBa_J23103 BBa_B0034]. The primers were designed that the FW and the RV primers ligate to a short oligonucleotide with overhanging restriction site ends for ''Eco''RI and ''Spe''I. So we don’t have to cut the ligated primers, because the sites should appear with the correct annealing. The goal was to clone the different promoters, the PCR product with the different laccase genes with HIS-Tag with prefix and suffix in pSB1C3 in one ligation step.
| + | |
| | | |
- | :*Additionally we want to produce the constructs with a new t7 promoter. After our laccases were not expressed we now think that maybe the RBS BBa_B0034, which we changed from originally 5'aAagaggagaaa3' to 5'aGagaggagaaa3' is not or to less recognized from ribosomes in the cells. This is the case, because for designing our T7 promoter overhanging ends for our primers we chose the same sequence as the Bielefeld Team before for example in their part [http://partsregistry.org/Part:BBa_K525710 BBa_K525710]. But another sequence for a T7 promoter, which is described in the Parts Registry was the sequence of the part [http://partsregistry.org/Part:BBa_I719005 BBa_I719005]. So we changed the sequence they used in their part BBa_K525710 from 5'taatacgactcactatagggaAagaggagaaaa 3' to 5’taatacgactcactatagggaGagaggagaaaa 3’ and used this sequence in our primers so the T7 sequence is the one from part [http://partsregistry.org/Part:BBa_I719005 BBa_I719005].
| + | </style> |
- | We have a primer pair from last year with the T7 promoter sequence with RBS BBa_B0034. The primers can be annealed to an oligonucleotide. After boiling the primers and cooling down there should be an oligonucleotide with an EcoRI and a SpeI restriction site. We now want to assemble the promoter the laccase genes and the pSB1C3 vector in one step. The pSB1C3 backbone was digested with ''Eco''RI and ''Pst''I, the laccases with ''Xba''I and ''Pst''I, and the promoter has the restriction sites ''Spe''I and ''Eco''RI.
