ZinT protein domain

In molecular biology, ZinT (formerly known as YodA) is a family of protein domains found in prokaryotes. The domain contains a single binding site that can accommodate a divalent cation, with a geometry suggestive of zinc binding. This family was first thought to be part of the bacterial response to a toxic heavy metal cadmium by binding to the metal to ensure its elimination; however, more recent work has suggested a role in zinc homeostasis.
