CspA (Polaribacter irgensii)

CspA K538003

CspA was used by team [http://2011.igem.org/Team:Amsterdam Amsterdam 2011] to create CryoBricks; cold resistance BioBricks. It encodes the CspA protein of Polaribacter irgensii, a homolog to E. coli's endogenous CspA and CspD. It's highly similar to P. irgensii 's CspC protein, which was also submitted to the registry. (BBa_K538004) See also the Main Page, or the team's [http://2011.igem.org/Team:Amsterdam/Project/Description Project Description] for further information.

Design Notes

The [http://www.ncbi.nlm.nih.gov/nuccore/88802191?from=707212&to=707403&report=gbwithparts sequence] of Polaribacter irgensii 's CspA protein was published by Murray et al. after shotgun sequencing its entire genome.[http://www.ncbi.nlm.nih.gov/nuccore/NZ_AAOG01000002] Team [http://2011.igem.org/Team:Amsterdam Amsterdam 2011] selected it for use in their CryoBricks following Uh et al. publishing they rescued a cold-sensitive E. coli by overexpressing this protein, greatly enhancing its freeze/thaw cycle survival rate. Pre- and suffixes were added to the sequence 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.
