Document Summary

Conversed in prokaryotes , chloroplasts, and some mitochondria. Cellular localization of bacterial cytoskeleton proteins required for cell division and maintenance of cell shape: the tubulin-like ftsz and the actin-like ftsa are essential cell division proteins in spherical s. aureus (a). Rod-shaped e. coli (b), and crescent-shaped c. crescentus (c) cells. During cell division, ftsz and ftsa localize at mid-cell in a ring-like structure, the divisome (indicated by the dotted lines). The actin-like mreb is present in elongated (rod-shaped) cells & forms intracellular helical filaments (indicated by the dashed black line).
