Escherichia coli can form linear trails and move in a flagellum-independent manner on semisolid agar containing carbon sources. Trail formation seemed to correlate with the growth speed and/or carbon metabolism. Cell morphology in linear trails changed into larger cell sizes. We speculate that the flagellum-independent trail formation is a new mechanism for migration of E. coli cells.
The structure of E. coli core RNA polymerase (RNAP) has been determined to approximately 23 A resolution by three-dimensional reconstruction from electron micrographs of flattened helical crystals. The structure reveals extensive conformational changes when compared with the previously determined E. coli RNAP holoenzyme structure, but resembles the yeast RNAPII structure. While each of these st...
