Distribution of shufflon among IncI plasmids.
A shufflon or clustered inversion is a novel type of DNA rearrangement originally discovered in the IncI1 plasmid R64 (T. Komano, A. Kubo, and T. Nisioka, Nucleic Acids Res. 15:1165-1172, 1987). In a 1.95-kilobase region of R64 DNA, four DNA segments inverted independently or in groups, resulting in a complex DNA rearrangement. We found similar types of shufflon in other IncI1 plasmids, includi...
متن کاملPurification and characterization of thin pili of IncI1 plasmids ColIb-P9 and R64: formation of PilV-specific cell aggregates by type IV pili.
Thin pili of the closely related IncI1 plasmids ColIb-P9 and R64 are required only for liquid mating and belong to the type IV family of pili. They were sedimented by ultracentrifugation from culture medium in which Escherichia coli cells harboring ColIb-P9- or R64-derived plasmids had been grown, and then the pili were purified by CsCl density gradient centrifugation. In negatively stained thi...
متن کاملThe kind of group you want to belong to: Effects of group structure on group accuracy
There has been much interest in group judgment and the so-called 'wisdom of crowds'. In many real world contexts, members of groups not only share a dependence on external sources of information, but they also communicate with one another, thus introducing correlations among their responses that can diminish collective accuracy. This has long been known, but it has-to date-not been examined to ...
متن کاملTransferable antibiotic resistance plasmids from biogas plant digestates often belong to the IncP-1ε subgroup
Manure is known to contain residues of antibiotics administered to farm animals as well as bacteria carrying antibiotic resistance genes (ARGs). These genes are often located on mobile genetic elements. In biogas plants (BGPs), organic substrates such as manure and plant material are mixed and fermented in order to provide energy, and resulting digestates are used for soil fertilization. The fa...
متن کاملProperties of the relaxation complexes of supercoiled deoxyribonucleic acid and protein of the R plasmids R64, R28K, and R6K.
The presence of supercoiled deoxyribonucleic acid in the form of a relaxation complex is described for the antibiotic resistance plasmids R64, R28K, and R6K. The properties of these relaxation complexes indicate that they consist of a covalently closed circular deoxyribonucleic acid molecule associated with an activable, single strand-specific endonuclease.
