MICROM 410 Lecture Notes - Lecture 5: Magnetotactic Bacteria, Magnetosome, Atp Hydrolysis
Document Summary
There are proteins associated with the ms ring called motor proteins (motb in diagram). This is a channel that allows protons to ow down their concentration gradient and release energy. It is thought that as proteins pass through the mot proteins, it moves the basal body (repels) Flig proteins: switch proteins, can turn agella clockwise or counterclockwise. Archaeal agellum is spun by the hydrolysis of atp, it is thinner and not hollow. Through atp hydrolysis, cells slide the laments relative to one another, producing a beating motion that allows the eukaryotic organism to move. Possess an endo agellum - found in between the cell membrane instead of protecting out. They still have a basal body and still rotate. Rotation exerts pressure on the outer membrane, which starts rotating in the opposite direction. The tension between the membrane and the viscous environment provides traction for the spirochete as it corkscrews its way through.
