Part:BBa_K1321308

pBla-Vhb-122-Bb

pBBR122-Bb is a broad-host range plasmid capable of replication in E. coli and several other Gram- species. It is also capable of replication in cellulose-producing bacterium Gluconacetobacter xylinus (Figure 1 - here, pBBR122-Bb is used as a backbone for pBla-Vhb-122, and data for pBla-Vhb-122 is presented), and can be used as a shuttle vector for G. xylinus genetic engineering. BBa_K1321308 is a part of the G.xylinus toolkit (parts BBa_K1321295 - BBa_K1321332).

Figure 1. Confirmation of pSEVA321, pSEVA331, pSEVA351, pBla-Vhb-122 and pBAV1K ability to replicate in G.xylinus.. pBBR122 (pBla) can replicate in G.xylinus. G.xylinus igem strain was transformed with pBRR 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.

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

NOTE: Because the registry's standard plasmid backbone pSB1C3 is not capable of replication in Gluconacetobacter species, the G.xylinus 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 G.xylinus toolkit available for the synthetic biology community, Imperial iGEM 2014 team has made it freely available upon request, with quality control provided (see Experience). To request, please contact Imperial iGEM 2014 team.
