pSEVA331-Bb - pSEVA331 with biobrick prefix and suffix

This is pSEVA331 converted into a biobrick compatible format by substituting the original multiple cloning site for biobrick prefix and suffix. pSEVA331 is a broad host range plasmid, capable of replication in E.coli and several other organisms. It is capable of replication in the cellulose producing bacteria Komagataeibacter rhaeticus and Gluconacetobacter xylinum. We have used it as our standard backbone for Komagataeibacter genetic engineering, in the Komagataeibacter toolkit (parts BBa_K1321295 - BBa_K1321332).

Figure 1. Confirmation of pSEVA321, pSEVA331, pSEVA351, pBla-Vhb-122 and pBAV1K ability to replicate in K. rhaeticus. K. rhaeitucs iGEM strain was transformed with pSEVA331-Bb using electroporation. Transformed cells were plated out on HS-Cam plates. Single colonies were then picked and grown in 5ml HS-cellulose medium (in 50ml Corning tubes) at 180rpm, 30C for 3 days. Cultures were then miniprepped using Qiagen DNA mini kit (see protocol here)". Miniprepped DNA was then used as template for pSEVA-specific primers. PCR products were visualized using 1% agarose gel, 100V, 20min. Ladder - NEB 2logL, expected band size for positive control - 328bp; size of lowest bright band of the ladder-500bp.

Komagataeibacter toolkit was designed to ease genetic engineering of cellulose-based biomaterials using the cellulose synthesizing bacterium Komagataeibacter rhaeticus iGEM (parts Bba_K1321305 and BBa_K1321306). As no registry parts had been tested in K. rhaeticus, the aim of this toolkit was to determine the parts usable in K. rhaeticus and to characterize them in this host. pSEVA331-Bb is a non-standard broad host range plasmid capable of replication in K. rhaeticus and E. coli (a shuttle vector) and was selected because the registry's standard plasmid backbone pSB1C3 can not be used for K. rhaeticus engineering.

NOTE: Because the registry's standard plasmid backbone pSB1C3 is not capable of replication in Komagataeibacter or Gluconacetobacter species, the Komagataeibacter genetic engineering toolkit is housed mainly in pSEVA331-Bb. pSEVA331-Bb is a non-standard backbone, which therefore can't be quality controlled by and maintained in the Registry. However, in order to make the Komagataeibacter toolkit available for the synthetic biology community, Imperial iGEM 2014 team has made it freely available in AddGene or upon request.
