InterPro domain: IPR012312

This entry represents a haemerythrin cation-binding domain that occurs [ 1 ] in haemerythrins, myohemerythrins and related proteins. This domain binds iron in haemerythrin, but can bind other metals in related proteins, such as cadmium in a Nereis diversicolor protein ( P80255 ) [ 2 ]. This domain is also found in Repair of iron centres or Ric proteins [ 3 ].
