“…Although cell division machinery is generally well conserved in eubacteria, mycobacteria lack genes encoding several wellcharacterized regulatory proteins, e.g., EzrA, ZapA, ZapB, SulA, and MinCDE, and also some integral components, e.g., FtsA, FtsN, and FtsB (30). Despite this fact, the slow polymerization and weak GTP hydrolysis activities of M. tuberculosis FtsZ combined with the presence of novel proteins such as ChiZ and FipA, which indirectly or directly modulate FtsZ ring assembly, impart uniqueness to the mycobacterial cell division machinery (6,7,45,52).…”
