Abstract
The present invention provides an expression vector comprising an RK2 minimum replicon together with an expression cassette comprising the regulatory functions of a TOL plasmid, and, in particular, an expression vector comprising a RK2 minimum replicon together with a promoter Pm and/or Pu and a corresponding regulatory gene xylS and/or xylR as derived from a TOL plasmid. Such expression vectors may be used to express desired genes in a wide range of gram negative and gram positive bacterial hosts.
