Type IV pili (Tfp) mediate the movement of bacteria over surfaces without the use of flagella.
These movements are known as social gliding in Myxococcus xanthus and twitching in …

▪ Abstract The mechanisms responsible for bacterial gliding motility have been a mystery for
almost 200 years. Gliding bacteria move actively over surfaces by a process that does not …

Type IV pili are part of a widespread superfamily of bacterial and archaeal cell surface
structures important for biofilm formation, motility, host adhesion, predation, DNA uptake …

Cheating is a potential problem in any social system that depends on cooperation and in
which actions that benefit a group are costly to individuals that perform them,,,,. Genetic …

The type II secretion pathway or the main terminal branch of the general secretion pathway,
as it has also been referred to, is widely distributed among Proteobacteria, in which it is …

Twitching motility is a form of solid surface translocation which occurs in a wide range of
bacteria and which is dependent on the presence of functional type IV fimbriae or pili. A …

Background Many microorganisms, including myxobacteria, cyanobacteria, and
flexibacteria, move by gliding. Although gliding always describes a slow surface-associated …

The myxobacteria are Gram-negative organisms that are capable of multicellular, social
behaviour. In the presence of nutrients, swarms of myxobacteria feed cooperatively by …

Myxobacteria are predatory and are prolific producers of secondary metabolites. Here, we
tested a hypothesized role that secondary metabolite antibiotics function as weapons in …

Electron cryotomography (ECT) provides three-dimensional views of macromolecular
complexes inside cells in a native frozen–hydrated state. Over the last two decades, ECT …
