Goal: Design plasmids that express agaA construct
Procedure:
Using Geneious, we first created the agaA construct:
- Promoter BBa_J23108 from the Anderson's promoter collection
- RBS from the RBS Calculator of Salis lab specific for E coli
- BioBrick Prefix + Scar from the iGEM Parts webpage
- agaA sequence codon optimized for E coli 12 (IDT online tool). We checked with Generious that there were no restriction sites for EcoRI, SpeI, ZbaI and PstI.
- Histidine tag: 6 Histidines in C-terminal were added
- Stop codon
- BioBrick scar + BioBrick suffix from the iGEM Parts webpage
To amplify this construct, we created two oligos:
Name | Sequence (5'->3') | Notes | Binding position |
oPB.001 | TATAGAATTCGCGGCCGCTTCTAGAGTGACAGCTAGCTCAGTCCTAGG | agaA forward for BioBrick vector | 1->23 |
oPB.002-BAD PRIMER | GAAGCATCATCACCATCACCACTGATACTAGTAGCGGCCGCTGCAGTTA | agaA REVERSE for BioBrick vector- NOT REVERSED | 1272->1296 |
oPB.005 | TTAACTGCAGCGGCCGCTACTAGTATCAGTGGTGATGGTGATGATGCTTC | agaA reverse for BioBrick vector | 1272->1296 |
* We noticed the 16/06/2014 that oPB.002 was NOT reversed and we designed oPB.005
Tip: When creating oligos: we add 4 nt at the beginning and the end composed by AT, to make sure the enzyme will bind properly.
We chose two backbones for the construct:
- pSB1C3 from the iGEM Parts to create a BioBrick.
- pEC-XC99E, a E coli-C glutamicum shuttle plasmid
We designed two plasmids:
1. pPB.001: Biobrick submission of agaA expression construct
1) Plasmid pSB1C3: High copy BioBrick assembly plasmid. Constitutive expression. To use in E coli
2) agaA construct
2.pPB.002:agaA expression construct. Shuttle vector E coli-C glutamicum
oPB.003 | 5'-CTGCAGATGCAAGCTTGGCTGTTTTGGCG-3' | PstI site + agaA forward for pEC-XC99E |
oPB.004 | 5'-TCTAGACACCACCCTGAATTGACTCTCTTC-3' | XbaI site + aga reverse for pEC-XC99E |
2) agaA construct
June 16th
Goal: Design new reverse oligo for Biobrick construction
Procedure:
We noticed oPB.002 was NOT reverse and therefore could not be used. We created oPB.005 instead:
oPB.005 | 5'-TTAACTGCAGCGGCCGCTACTAGTATCAGTGGTGATGGTGATGATGCTTC-3' | agaA reverse for BioBrick vector |
1272->1296 |

- Use fusion polymerase, as it is more reliable than the DreamTaq we used. DreamTaq is more for colony PCR.
- Final concentration of 200 uL, to have more DNA
-
When PCR does not work we look at:
- Annealing temperature: we start typically at 52ºC and can go down to 50ºC.
- DMSO concentration: typically 3%. Avoids missmatching
- Extension time, according to the manufacturer

Goal:Culture Corynebacterium glutamicum and Corynebacterium striatum
Procedure:
We will open the flask that arrived and culture Corynebacterium in Tryptophan Soy liquid medium at 37ºC overnight. After, we will plate them and culture single colonies to make competent cells and transform them. Corynebacterium glutamicum is sPB.006 and Corynebacterium striatum is sPB.007.

Procedure:
Yesterday July 15th Juanma runned a colony PCR with oPB.001 and oPB.005 using the
Phusion Polymerase protocol. Today we will run a 1% agarose gel with the purified DNA following the
standard protocol.
Results:
There are no bands on the gel. This might happen with Colony PCR. To double-check, we will do a MiniPrep to extract pPB.001 and run a PCR with oPB.001 and oPB.005.Goal:Make competent Corynebacterium

DNA Kit Plate Instructions
Before you use the DNA in the Distribution Kit Plates, be sure to test the efficiency of your competent cells with the
Transformation Efficiency Kit.
To use the DNA in the Distribution Kit, follow these instructions:
Note: There is an estimated 2-3ng of DNA in each well, following this protocol, assume that you are transforming with 200-300pg/ul
-
- With a pipette tip, punch a hole through the foil cover into the corresponding well of the part that you want. Make sure you have properly oriented the plate . Do not remove the foil cover, as it could lead to cross contamination between the wells.
- Pipette 10uL of dH2O (distilled water) into the well. Pipette up and down a few times and let sit for 5 minutes to make sure the dried DNA is fully resuspended. We recommend that you do not use TE to resuspend the dried DNA.
- Transform 1ul of the resuspended DNA into your desired competent cells, plate your transformation with the appropriate antibiotic* and grow overnight.
- Pick a single colony and inoculate broth (again, with the correct antibiotic) and grow for 16 hours.
- Use the resulting culture to miniprep the DNA AND make your own glycerol stock (for further instruction on making a glycerol see this page). We recommend using the miniprepped DNA to run QC tests, such as restriction digests and sequencing.
* To know which antibiotics to use, look at the plasmid that the part is in. The naming scheme for plasmids is specifically designed to indicate antibiotic resistance.
Note: There is not enough DNA in each well to perform anything but transformations
