FtsZ functions at an early stage of septum formation.

Early in the division cycle, FtsZ is localized throughout the cytoplasm, but prior to cell division FtsZ becomes localized in a ring around the circumference at the mid-cell position.

The structure is called the Z-ring.

Eukaryotic cells have two isozymes of aconitase

• The mitochondrial isozyme (convert citrate to isocitrate in the citric acid cycle)

• The cytosolic isozyme
