Iâm way late with this on March 9th but Iâve watched Paul Kangas for years! He has always epitomized the NBR to me and I will sorely miss him. He was always sharp and crisp and on point.
the bacterial cytoskeleton and cell shape-determining proteins such as MreC, function in concert to orches-trate the localization of cell wall synthetic complexes resulting in spatially co-ordinated and efficient pepti-doglycan synthetic activity. Introduction The distinct morphology of most bacterial cells is dictated by the architecture of the peptidoglycan cell wall. In Gram-negative bacteria, the cell wall is thought to be a single
For example, bacillus-shaped bacteria that have an inactivated MreB gene become coccoid shaped, and coccus-shaped bacteria naturally lack the MreB gene. Most bacteria come in one of three basic shapes: coccus, rod or bacillus, and spiral.acterial cell shape is determined primarily by a protein called MreB. MreB forms a spiral band â a simple cytoskeleton â around the interior of the cell just under the cytoplasmic membrane. It is thought to define shape by recruiting additional proteins that then direct the specific pattern of bacterial cell growth.
