Flagellar Motor Transformed: Biophysical Perspectives of the Myxococcus xanthus Gliding Mechanism

open access: yesFrontiers in Microbiology, 2022
Many bacteria move on solid surfaces using gliding motility, without involvement of flagella or pili. Gliding of Myxococcus xanthus is powered by a proton channel homologous to the stators in the bacterial flagellar motor. Instead of being fixed in place

The toxoplasma Acto-MyoA motor complex is important but not essential for gliding motility and host cell invasion.

open access: yesPLoS ONE, 2014
Apicomplexan parasites are thought to actively invade the host cell by gliding motility. This movement is powered by the parasite's own actomyosin system, and depends on the regulated polymerisation and depolymerisation of actin to generate the force for

A unique profilin-actin interface is important for malaria parasite motility. [PDF]

open access: yesPLoS Pathogens, 2017
Profilin is an actin monomer binding protein that provides ATP-actin for incorporation into actin filaments. In contrast to higher eukaryotic cells with their large filamentous actin structures, apicomplexan parasites typically contain only short and ...

Malaria parasite LIMP protein regulates sporozoite gliding motility and infectivity in mosquito and mammalian hosts

open access: yeseLife, 2017
Gliding motility allows malaria parasites to migrate and invade tissues and cells in different hosts. It requires parasite surface proteins to provide attachment to host cells and extracellular matrices. Here, we identify the Plasmodium protein LIMP (the

Colony spreading of the gliding bacterium Flavobacterium johnsoniae in the absence of the motility adhesin SprB

open access: yesScientific Reports, 2021
Colony spreading of Flavobacterium johnsoniae is shown to include gliding motility using the cell surface adhesin SprB, and is drastically affected by agar and glucose concentrations.

MasABK proteins interact with proteins of the type IV pilin system to affect social motility of Myxococcus xanthus. [PDF]

open access: yesPLoS ONE, 2013
Gliding motility is critical for normal development of spore-filled fruiting bodies in the soil bacterium Myxococcus xanthus. Mutations in mgl block motility and development but one mgl allele can be suppressed by a mutation in masK, the last gene in an ...

Potential Role of Flavobacterial Gliding-Motility and Type IX Secretion System Complex in Root Colonization and Plant Defense

open access: yesMolecular Plant-Microbe Interactions, 2014
Members of the Flavobacterium genus are often highly abundant in the rhizosphere. Nevertheless, the physiological characteristics associated with their enhanced rhizosphere competence are currently an enigma.

Gliding Motility: The Molecules behind the Motion [PDF]

open access: yesCurrent Biology, 2003
In apicomplexan parasites, gliding motility and host cell invasion are driven by an actomyosin-based system. Recent studies have characterized several components of the gliding motility apparatus and have provided new insight into the molecular architecture of this locomotory system.

Structures of the Toxoplasma gliding motility adhesin [PDF]

open access: yesProceedings of the National Academy of Sciences, 2014
Significance Structures of the major adhesin in Toxoplasma show how its ligand-binding domain is displayed above the cell surface at the tip of a stalk with six elongated domains. A prodomain inhibits conformational change from closed to open. An associating protein binds to

Motility and self-organization of gliding Chlamydomonas populations

open access: yesPhysical Review Research, 2022
Cellular appendages such as cilia and flagella represent universal tools enabling cells and microbes, among other essential functionalities, to propel themselves in diverse environments.
