Structural Biologists Get First Picture of Complete Bacterial Flagellar Motor

When it comes to tiny motors, the flagella used by bacteria to get around their microscopic worlds are hard to beat. Composed of several tens of different types of protein, a flagellum (that's the singular) rotates about in much the same way that a rope would spin if mounted in the chuck of an electric drill, but at much higher speeds-about 300 revolutions per second.
