Aconitase

The enzyme system bringing about the reversible hydration of cisaconitic acid has been shown to be different from fumarase and termed "aconitase".

These are: aconitase, isocitric dehydrogenase, alpha-ketoglutaric dehydrogenase, succinic dehydrogenase, fumarase, malic dehydrogenase, DPHN-oxidase, and cytochrome oxidase.

The best-characterized member of iron-sulfur isomerases is mitochondrial aconitase.
