It is indeed loosely coiled, like a pulled-out, left-handed spring, or perhaps a corkscrew, and it terminates close to the cell wall, as thickened, flexible zone, called a hook because it is usually bent . . The remarkable feature is the way in which the flagellum and its hook are anchored. In a bacterium called Bacillus subtilis, which has a fairly simple structure, the hook extends, as a rod, through the outer wall, and at the end of the rod, separated by its last few nonometers, are two discs . . In effect, the long flagellum seems to be held in place by its hook, with two discs acting as a double bolt, or perhaps a bolt and washer." -- *John Postgate, The Outer Reaches of Life, p. 160. =============================== }, day = {25}, keywords = {adaptations, complex, complexity, evolution, exaptation, flagellum, matzke, pallen, zimmer}, month = {March}, pages = {1--276}, posted-at = {2007-03-23 20:41:24}, priority = {5}, publisher = {Cambridge University Press}, title = {The Outer Reaches of Life}, url = {http://www.amazon.com/Outer-Reaches-Life-John-Postgate/dp/0521440106}, year = {1994} }
