Seminar-A contrasting tale of dynamics: How two different polymers define the shape of bacteria and divide them in half
presents a seminar by:
Abstract: The shape of bacteria is determined by their cell wall, a crosslinked macromolecule that holds them in shape. To grow in defined shapes, or divide half, bacteria must add material into this structure in a spatially controlled manner. The activity of the enzymes that build the cell wall is regulated by small dynamic filaments, homologs of eukaryotic cytoskeletal proteins. We study the emergent actions of these polymer/enzyme systems by observing their in vivo dynamics while conducting chemical and genetic manipulations. These dynamics have revealed the polymers controlling cell elongation and division function in very different ways.
