title: Construction of improved Escherichia-Pseudomonas shuttle vectors derived from pUC18/19 and sequence of the region required for their replication in Pseudomonas aeruginosa.
abstract: The nucleotide sequence of the 1.9-kb PstI fragment from pRO1614, that allows stable maintenance of pMB1 (ColE1)-based cloning vectors in Pseudomonas, was determined. This fragment encodes a putative origin of replication (ori), a replication-controlling protein, and the C terminus of the Tn3 beta-lactamase-encoding gene. Improved versions of the broad-host-range plasmid vectors, pUCP18 and pUCP19, were constructed by deletion of nonessential DNA or replacement of nonessential DNA with an antibiotic-resistance cassette.
