The Biobricks Foundation: RFC
Investigators: Chris W., Bea, Kira, Hanna, Julian, Anna, Jessica (Tobias,Sven, Kristian)
The BioBricks Foundation is dedicated to promoting and protecting the open development,
sharing, and reuse of BioBrick™ standard biological parts.
Homepage: http://openwetware.org/wiki/The_BioBricks_Foundation:RFC
Two important standarts:
BBF RFC-10:
This standard defines the required sequence properties for a Biobrick(tm) standard biological part.
http://dspace.mit.edu/bitstream/handle/1721.1/45138/BBFRFC10.txt?sequence=1
BBF RFC-25: Fusion Protein (Freiburg) Biobrick assembly standard
This Request for Comments (RFC) describes an extension to the original BioBrick assembly standard (BBF RFC 10).

Theoretical cloning
DNA- and protein-analyse:
- Thymidin Kinase HSVI
Accesion: V00470 (Genebank) CDS without iGEM-restriction site, unkown sequence in front of CDS with an EcoRI-restriction site, sequence from 1980! (there are a lot of X-ray analysis, but just to be on the safe side we should check the sequence)
- Cytosine Deaminase (see also FCY1) (S.cerevisae)
Accession number: AF005261 (Genebank)
CDS without iGEM-restriction site, unkown in front of CDS with PstI-restriction site, sequence from 1997
- pORF-CodA::upp (E.coli) [Vektor from InvivoGen]
CDS of the Cytosine Deaminase (E.coli) without iGEM-restriction site
- Alignment of the amino acid-sequences of the cytosin deaminases of E.coli (Invivogen) and S.cerevisiae (Genebank)
no consensus found at the amino acid-sequence
discussion at the next meeting
3. Labday 15.04.2010
Theoretical cloning
Investigators: Kira, Johannes, Bea
- pAAV-MCS vector (Stratagene): we survey the vector for igEM-restiction sites (RFC-25)
EcoRI 1327; Xbal 1344; are inside the MCS
NgoMIV 2254 are inside the V1 Ori region
- function of the Beta-Globin intron ( pAAV MCS Vector): increases the expression rate in Vivo/ Vitro with several mechanisms ( i.a. increased m-RNA accumulation
(Media: Freigem10_Nott_et_al_A_quantitative_analysis_of_intron_effects_on_mammalian_gene_expression_2003.pdf?; Media: Freigem10_Haddad_et_al_A_systematic_study_of_the_function_of_the_h-beta-globin_introns_on_the_expression_2009.pdf?)
- Thymidin Kinase : we received another modified thymídin kinase-sequence from Amor, to do: check for iGEM restriction sites and develop a cloning strategie
4. Labday 22.04.2010
Theoretical cloning
Investigators: Adrian, Chris W., Hanna, Bea
- tomorrow we will obtain the vector sequence for the thymidinkinase (WT) from Amor
- call at Stratagene: #240071 AAV-Helper Free System, 1412 € (netto), available until next week ; we asked for a discount (Bea got Infos per E-mail)
- next step (tomorrow, 10 am): modification of the multiple cloning site
5. Labday 23.04.2010
Theoretical cloning
Investiators: Adrian, Chris W., Hanna, Kerstin, Anissa, (Kristian, Tobias, Sven)
- thymidin kinase from Amor: there is a PstI restriction site within the sequence (instead of this kinase we will probably utilize the TK30 + SR39 mutant -> we have to find their sequences )
- analyze of the secundary struckture of the ITR's (pAAV MCS of Stratagene), to decide if we can perform a point mutation to delete the PstI-restriction site :

- sequence alignement of the beta-globin of the pAAV MCS Plasmid with human beta-globin:
http://www.molbiotech.uni-freiburg.de/iGEM/wiki2010/images/8/83/Freiburg10_Nucleotide_alignment_221_extraction.pdf
- To do: gather informations about the mutant thymidinkinase (TK30 + SR39)
we won't use this kinase...
