| Further information: | This IncP, broad-host-range plasmid was constructed as follows: pJBpn25LUC was digested with SalI and religated. pJBpn25LUC2 contains the lacI(q) promoter in the opposite orientation relative to the luciferase cassette. This construct avoids transcription of luciferase originating from the constitutive lacI(q) promoter. The expression of the luciferase gene is controlled by the IPTG inducible T5 N25/O2 promoter. The promoter/operator element T5 N25/O2 consists of the highly efficient E. coli phage T5 N25 promoter and two lac operator sequences (Bujard et al. (1987)). Due to the presence of the lacI(q) (repressor)-N25/O2 (promoter/operator) cassette on the plasmid, regulated (IPTG inducible) expression should be possible in a wide range of Gram-negative hosts. The plasmid RK2 trfA gene encodes two polypeptide products P382 and P285 of 382 and 285 amino acids respectively, using a different initiation codon within the same reading frame. The resulting protein is essential for vegetative replication. Introduce the plasmid by electroporation, or through conjugation, using plasmid RK2/RP4 transfer functions (provided in trans by RK2/RP4, RK2/RP4-derived vectors, other replicons carrying RK2/RP4 transfer functions (e.g. pRK2073) or strains expressing the tra genes of RK2/RP4). |
