Ethylenediamine Tetraacetic Acid is a polyamino carboxylic acid hexadentate ligand and a chelating agent.
Ethylenediamine Tetraacetic Acid is a chelator of divalent cations. It also inhibits enzymes, such as metalloproteases, that require divalent cations for activity.
Zinc-dependent metalloproteinases, as well as other proteases that are stabilized by calcium, can be effectively inhibited by chelation of divalent metal ions with EDTA. Other chelators such as EGTA, specific for calcium, and 1,10-phenanthroline, highly specific for zinc, can be used to target these two different types of proteases.
