The bacterial cytoskeleton is a network of protein filaments that helps maintain the shape and structure of bacterial cells. Unlike the complex cytoskeleton found in eukaryotic cells, the bacterial cytoskeleton is simpler and consists mainly of proteins such as FtsZ, MreB, and Cres. These proteins play crucial roles in cell division, shape determination, and maintaining cell integrity. In addition to structural support, the bacterial cytoskeleton is involved in various cellular processes, including cell division and cell wall synthesis. The dynamic nature of these protein filaments allows bacteria to adapt their shape in response to environmental changes, contributing to their survival and functionality.
