Plasmid-to-plasmid recombination in Haemophilus influenzae.
نویسندگان
چکیده
No recombination between plasmids was observed after conjugal transfer of a plasmid into a cell carrying another plasmid. Two types of such recombination took place after transformation, one type being Rec+ dependent and suggesting a preferred site of recombination. The other much rarer type was at least partially Rec+ independent.

rpe, a cis-acting element from the strA region of the Haemophilus influenzae chromosome that makes plasmid establishment independent of recombination.
Plasmids that share homology with the Haemophilus influenzae chromosome transform wild-type cells more efficiently than they transform recombination-defective mutants. A 5.2-kilobase-pair chromosomal fragment containing the strA gene of H. influenzae was found to promote efficient plasmid establishment in recombination-defective mutants. A cis-acting element in the insert, called rpe for rec-le...
متن کاملA plasmid cloning vehicle for Haemophilus influenzae and Escherichia coli.
A new plasmid cloning vehicle (pDM2) was used to introduce a library of Haemophilus influenzae chromosomal fragments into H. influenzae. Transformants of the highly recombination-defective rec-1 mutant were more likely to contain exclusively recombinant plasmids after exposure to ligated DNA mixtures than was the wild type. pDM2 could replicate in Escherichia coli K-12.
متن کاملSite-specific recombination with the chromosomal tRNA(Leu) gene by the large conjugative Haemophilus resistance plasmid.
Characterization of the sequences involved in recombination of the Haemophilus plasmid p1056 with the Haemophilus influenzae chromosome produced evidence indicating site-specific recombination with chromosomal tRNA(Leu). attP sequences identical to those of p1056 were found in six plasmids of diverse origin, suggesting that a family of Haemophilus plasmids recombines with chromosomal tRNA(Leu).
متن کاملLoss of plasmids containing cloned inserts coding for novobiocin resistance or novobiocin sensitivity in Haemophilus influenzae.
Plasmids pNov1 and pNov1s , coding for resistance and sensitivity to novobiocin, respectively, were readily lost from wild-type Haemophilus influenzae but retained in a strain lacking an inducible defective prophage. The plasmid loss could be partly or wholly eliminated by a low-copy-number mutation in the plasmid or by the presence of certain antibiotic resistance markers in the host chromosom...
متن کاملCloning of conserved regions of nontypeable Haemophilus influenzae hmw1 core binding domain
Colonization of nontypeable Haemophilus influenzae (NTHi) in nasopharynx causes respiratory tract disease. In 80% of clinical isolates, HMW proteins are the major adhesions and induce protective antibodies in the hosts. Therefore, it can be used as a vaccine candidate. The aim of this study is designing and cloning of the conserved regions of NTHi hmw1 core binding domain.In this study, the sta...
