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

  • 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

Theoretical cloning

  • 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:

  • To do: gather informations about the mutant thymidinkinase (TK30 + SR39)

we won't use this kinase...
