The ampicillin‐resistance transposon Tn3is the archetype (“Tn3” being synonymous with
“Tn1” or “Tn2”;(1)) of a large and widespread family of transposons with representatives in …

Bacterial plasmids encode partitioning (par) loci that ensure ordered plasmid segregation
prior to cell division. par loci come in two types: those that encode actin-like ATPases and …

FtsK acts at the bacterial division septum to couple chromosome segregation with cell
division. We demonstrate that a truncated FtsK derivative, FtsK 50C, uses ATP hydrolysis to …

In bacteria, two categories of specialised recombination promote a variety of DNA
rearrangements. Transposition is the process by which genetic elements move between …

Knots galore: With a judicious choice of ions and solvents, it is possible to amplify a
molecular Solomon link by kinetically controlled crystallization from a dynamic combinatorial …

Cre recombinase catalyzes site-specific recombination between two 34-bp loxP sites in a
variety of DNA substrates. At the start of the recombination pathway, the loxP sites are each …

The structure of the site‐specific recombinase, XerD, that functions in circular chromosome
separation, has been solved at 2.5 Å resolution and reveals that the protein comprises two …

Multicopy plasmids of Escherichia coli are distributed randomly at cell division and, as long
as copy number remains high, plasmid‐free cells arise only rarely. Copy number variation is …

A major determinant of Vibrio cholerae pathogenicity, the cholera enterotoxin, is encoded in
the genome of an integrated phage, CTXϕ. CTXϕ integration depends on two host-encoded …

Abstract We present TopoStats, a Python toolkit for automated editing and analysis of Atomic
Force Microscopy images. The program automates identification and tracing of individual …
