Shuttle Vector – An Expression Vector for Gram(+) and Gram(-) Prokaryotes

The heterologous expression of genes in prokaryotes can be challenging, especially if the genes originate from a distant host or if the source is uncertain, such as a metagenomic expression library. Many vectors have been developed based on broad host range origins of replication, but these tend to focus on either gram(+) or gram(-) prokaryotes. This invention regards the construction of a completely synthetic expression vector, namely pPolyREPII, based on both the pBBR1 and pWV01 origin of replication.
