A streptomycin and tetracycline resistance plasmid R64 isolated from Salmonella enterica serovar Typhimurium belongs to the incompatibility group I1 (IncI1). The DNA sequence of the R64 conjugative transfer region was described previously (Komano et al., 2000). Here, we report the complete genome sequence of R64. In the circular double-stranded R64 genome with 120,826bp, 126 complete ORFs are predicted...
Corynebacterium glutamicum is an industrial microorganism for production of amino acids. However, the metabolic engineering in C. glutamicum has been retarded due to lack of suitable vectors. In this study, we have constructed a shuttle vector pDXW-10 which harbors a large multiple cloning site suitable for cloning multiple genes, and a tac-M promoter suitable for constitutive gene expression in C...
The complete nucleotide sequence of pSRD192 plasmid from Selenomonas ruminantium 19D has been obtained and analyzed. The plasmid, 2334bp in length, was shown to replicate by rolling circle replication mechanism. By PCR method variability of pSRD192-like plasmids was investigated and another variant of pSRD192-like plasmid; the pSRM22 plasmid 2338bp in length; was detected and characterized. Both pSRD192...
Staphylococcus simulans biovar staphylolyticus contains five plasmids designated pACK1–pACK5. The complete nucleotide sequences of pACK1 (55171bp) and pACK3 (28613bp) were determined and sequence comparison revealed that the entire pACK3 sequence is present on pACK1 (99.98% identical on the nucleotide level) with the sequence unique to pACK1 located between sin and blaZ, which are adjacent in pACK3...
A new cryptic plasmid, named pMM101, in an environmental Pseudomonas sp. has been isolated, and its 2140-bp DNA sequence has been determined and analyzed. One open reading frame (Rep MM ) similar to the rep gene of the rolling-circle replicon (RCR) group VIII has been allocated in the replication region where a putative double-strand origin dso and single-strand origin sso could also be identified...
The conjugative transfer system of Yersinia enterocolitica 29930 present on the cryptic plasmid p29930 comprises a mating pore formation system (Mpf) related to that of the IncX plasmid R6K and a DNA transfer and replication system (Dtr) with close relationship to the mob region of the mobilizable plasmid CloDF13. Two regions of the transfer system were selected for more detailed analyses of basic...
We have previously reported on the development and assessment of the tetracycline inducible vector pMIND (Blokpoel et al., 2005). Here we report the development of improved pMIND vectors that exhibit both reduced basal transcription in the absence of inducer and increased fold induction in the presence of inducer. An amino acid change in the repressor protein, TetR(Z), produced a 6-fold reduction...
