Detailed explanation-1: -Their major discovery was x-ray crystallography, which showed that MreB had the actin fold and was assembled in the crystals into actin-like filaments. Later work has discovered multiple prokaryotic actins with a variety of cytoskeletal functions, although the functions of most are unknown.
Detailed explanation-2: -The eukaryotic cytoskeleton evolved from prokaryotic cytomotive filaments. Prokaryotic filament systems show bewildering structural and dynamic complexity and, in many aspects, prefigure the self-organizing properties of the eukaryotic cytoskeleton.
Detailed explanation-3: -(F) Suggested organization of cytoskeleton-associated cell wall-synthesizing proteins of E. coli. The cytoplasmic MreB cytoskeleton is linked via MreC and MreD to the PBP murein biosynthetic enzymes (107).
