Myxobacteria gliding motility requires cytoskeleton rotation powered by proton motive force.
Myxococcus xanthus is a Gram-negative bacterium that glides over surfaces without the aid of flagella. Two motility systems are used for locomotion: social-motility, powered by the retraction of type IV pili, and adventurous (A)-motility, powered by unknown mechanism(s). We have shown that AgmU, an A-motility protein, is part of a multiprotein complex that spans the inner membrane and periplasm...
متن کاملMutant analysis reveals a specific requirement for protein P30 in Mycoplasma pneumoniae gliding motility.
The cell-wall-less prokaryote Mycoplasma pneumoniae, long considered among the smallest and simplest cells capable of self-replication, has a distinct cellular polarity characterized by the presence of a differentiated terminal organelle which functions in adherence to human respiratory epithelium, gliding motility, and cell division. Characterization of hemadsorption (HA)-negative mutants has ...
متن کاملGliding motility of Mycoplasma pulmonis.
The gliding movements of freshly isolated Mycoplasma pulmonis cells were observed and measured. The motile cells had a characteristic appearance, an average speed of 0.4 to 0.7 micron/s, and a maximum speed of 1 micron/s.
متن کاملEnergetics of gliding motility in Mycoplasma mobile.
Mycoplasma mobile glides on surfaces at up to 7 microm/s by an unknown mechanism. We studied the energetics that power gliding by using a novel, growth medium-free system. We found that cells could glide in defined media if the glass substrate is preconditioned by exposure to horse serum. The active component that potentiates gliding is sensitive to proteinase K treatment. We used the defined m...
متن کاملGliding Motility: The Molecules behind the Motion
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.
