Caltech researchers get first 3-D glimpse of bacterial cell-wall architecture

...d removing the sacculi and flattening them in a very thin layer of water, postdoctoral scholar Lu Gan, the paper's first author, was able to image the peptidoglycan structure in three dimensions, which allows for a virtual 3-D tour of the bacterial sacculus. "What we saw were long skinny tubes wrapping around t...

...e to make great advances in this area. Presently, Dr. Weibel investigates how bacteria respond to the environment. He has found a way to control the peptidoglycan synthesis of Escherichia coli, which was shown by his ability to transform these cells into different shapes. Through this research he hopes to explo...
