The active site of Isocitrate dehydrogenase binds the NAD+ or an NADP+ molecule as well as an Mn+ or Ca2+. This metal ion seems to be essential for catalysis<ref>PMID:15173171.</ref>. Side chains of Asp 279 form hydrogen bonds with Ser94 (Human isocitrate dehydrogenase).

Across species these are not perfectly conserved by they are replaced with residues of similar properties and also are found in similar areas of the protein. Below is a picture of Porcine Active site with all of its residuals and ligands.
