Abstract
We developed transposon and cloning shuttle vectors for genetic manipulation of Pseudomonas and other gram-negative bacteria, exploiting the unique properties and the broad host range of the satellite bacteriophage P4. P4::Tn5 AP-1 and P4::Tn5 AP-2 are suicide transposon vectors which have been used for efficient Tn5 mutagenesis in Pseudomonas putida. pKGB2 is a phasmid vector with a cloning capacity of about 7.5 kb; useful unique cloning sites are SacI and SacII in the streptomycin resistance determinant and PvuI and XhoI in the kanamycin resistance determinant. pKGB4 is a cosmid derived from pKGB2 and carries the additional cloning site SmaI in the kanamycin resistance determinant; its cloning capacity is about 18 kb. These vectors and their recombined derivatives were transferred from Escherichia coli to P. putida by transduction and may be used for other bacterial species susceptible to P4 infection.Pubblicazioni consigliate
