Multi-copy plasmids in Escherichia coli are not randomly distributed throughout the cell but are present as clusters of plasmid molecules that are localized at preferred cellular locations. A plasmid RK2 derivative (pZZ15) that can be tagged with a g

Broad host range plasmid RK2 encodes two versions of its essential replication initiation protein, TrfA, using in-frame translational starts spaced 97 amino acids apart. The smaller protein, TrfA-33, is sufficient for plasmid replication in many bact

Two plasmids, 76 and 148 kb in size, isolated from Ruegeria strain PR1b were entirely sequenced. These are the first plasmids to be characterized from this genus of marine bacteria. Sequence analysis revealed a biased distribution of function among t

A 50,709-bp cryptic plasmid isolated from a marine Micrococcus has been sequenced and found to contain a number of putative mobile genetic elements. The coding regions for 11 putative transposases comprise approximately 17% of the total plasmid seque

Copy-number regulation of the broad-host-range plasmid RK2 is dependent on the plasmid-encoded initiator protein, TrfA, and the RK2 origin of replication. The handcuffing model for copy-number control proposes that TrfA-bound oris reversibly couple t

Naturally occurring plasmids isolated from heterotrophic bacterial isolates originating from coastal California marine sediments were characterized by analyzing their incompatibility and replication properties. Previously, we reported on the lack of

The TrfA protein encoded by the broad host range bacterial plasmid RK2 specifically binds to eight direct repeats (iterons) present at the plasmid replication origin to initiate DNA replication. Purified TrfA protein is largely in the form of a dimer

An in vivo screen was developed for the identification of mutants of the RK2 replication initiation protein, TrfA, that were altered in their binding to the iterons within the plasmid RK2 origin of replication. This assay is based on an antibiotic se

The TrfA proteins, encoded by the broad host range plasmid RK2, are required for replication of this plasmid in a variety of Gram-negative bacteria. Two TrfA proteins, 33 and 44 kDa in molecular mass (designated TrfA-33 and TrfA-44, respectively), ar
