Gliding ghosts of Mycoplasma mobile.
Several species of mycoplasmas glide on solid surfaces, in the direction of their membrane protrusion at a cell pole, by an unknown mechanism. Our recent studies on the fastest species, Mycoplasma mobile, suggested that the gliding machinery, localized at the base of the membrane protrusion (the "neck"), is composed of two huge proteins. This machinery forms spikes sticking out from the neck an...

متن کاملForce and velocity of mycoplasma mobile gliding.
The effects of temperature and force on the gliding speed of Mycoplasma mobile were examined. Gliding speed increased linearly as a function of temperature from 0.46 microm/s at 11.5 degrees C to 4.0 microm/s at 36.5 degrees C. A polystyrene bead was attached to the tail of M. mobile using a polyclonal antibody raised against whole M. mobile cells. Cells attached to beads glided at the same spe...
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 کاملDetailed Analyses of Stall Force Generation in Mycoplasma mobile Gliding.
Mycoplasma mobile is a bacterium that uses a unique mechanism to glide on solid surfaces at a velocity of up to 4.5 μm/s. Its gliding machinery comprises hundreds of units that generate the force for gliding based on the energy derived from ATP; the units catch and pull sialylated oligosaccharides fixed to solid surfaces. In this study, we measured the stall force of wild-type and mutant strain...
