FtsZ is a protein encoded by the ''ftsZ'' gene that assembles into a ring at the future site of the septum of bacterial cell division. This is a prokaryotic homologue to the eukaryotic protein tubulin. FtsZ has been named after "Filamenting temperature-sensitive mutant Z". The hypothesis was that cell division mutants of ''E. coli'' would grow as filaments due to the inability of the daughter cells to separate from one another. == History == Discovery of the bacterial cytoskeleton is fairly recent. FtsZ was the first protein of the prokaryotic cytoskeleton to be identified. The gene was discovered in the 1950s by Y. Hirota (:ja:廣田幸敬) and his colleagues in a screen for bacterial cell division mutants. In 1991 it was shown by Erfei Bi and Joseph Lutkenhaus that FtsZ assembled into the Z-ring. Nuclear-encoded FtsZ in the moss ''Physcomitrella patens'' is required for chloroplast division and was the first identified protein essential for organelle division.〔R. Strepp, S. Scholz, S.
