Spatial organization is a hallmark of all living systems. Even bacteria, the smallest forms of
cellular life, display defined shapes and complex internal organization, showcasing a highly …

Many biologically important macromolecules undergo motions that are essential to their
function. Biophysical techniques can now resolve the motions of single molecules down to …

A molecular motor is made of either a single macromolecule or a macromolecular complex.
Just like their macroscopic counterparts, molecular motors “transduce” input energy into …

Molecular motors are diverse enzymes that transduce chemical energy into mechanical
work and, in doing so, perform critical cellular functions such as DNA replication and …

The study of chromosome segregation in bacteria has gained strong insights from the use of
cytology techniques. A global view of chromosome choreography during the cell cycle is …

DNA pumps play important roles in bacteria during cell division and during the transfer of
genetic material by conjugation and transformation. The FtsK/SpoIIIE proteins carry out the …

Summary The FtsK/SpoIIIE family of ATP-dependent DNA transporters mediates proper
chromosome segregation in dividing bacteria. In sporulating Bacillus subtilis cells, SpoIIIE …

Bacteria that have a circular chromosome with a bidirectional DNA replication origin are
thought to utilize a 'replication fork trap'to control termination of replication. The fork trap is an …

The translocation of DNA during bacterial cytokinesis is mediated by the SpoIIIE/FtsK family
of proteins. These proteins ensure efficient chromosome segregation into sister cells by ATP …

Dimeric circular chromosomes, formed by recombination between monomer sisters, cannot
be segregated to daughter cells at cell division. XerCD site-specific recombination at the …
