SheDnaK (Shewanella sp. Ac10)

SheDnaK K538002

SheDnaK was used by team [http://2011.igem.org/Team:Amsterdam Amsterdam 2011] to create CryoBricks; cold resistance BioBricks. It encodes the DnaK of Shewanella sp. Ac10, a homolog of E. coli 's own DnaK that's active at lower temperatures. See also the Main Page, or the team's [http://2011.igem.org/Team:Amsterdam/Project/Description Project Description] for further information.

Design Notes

Prefacing Yoshimune et al. 's publication regarding SheDnaK 's activity relative to that of E. coli 's endogenous DnaK[http://www.springerlink.com/content/f50n0gahppxacytb/], this protein's [http://www.ncbi.nlm.nih.gov/nuccore/AY728897.1 sequence] was published. Pre- and suffixes were added to this as clarified in OpenWetWare's [http://openwetware.org/wiki/Biobrick_standard BioBrick standards] and, as is recommended, the TAA stop codon was replaced with TAATAA. The sequence's conformity with Assembly standard 10 and putative future standards was ensured using the [http://bioweb2.pasteur.fr/docs/EMBOSS/recoder.html EMBOSS recoder], by recoding restriction sites of EcoRI, XbaI, SpeI, PstI, NotI, PvuII, XhoI, AvrII, NheI and SapI. Note that to ensure compatibility with [http://dspace.mit.edu/handle/1721.1/46747 RFC 21] and [http://dspace.mit.edu/handle/1721.1/45140 RFC 25], an additional 4 restriction sites must be recoded. For RFC 21 compatibility, no BamHI or BglII sites may be present in the sequence. Likewise, for RFC 25, no AgeI or NgoMIV sites may occur.
