Heavy Metal Binding Domain
This family includes copper/mercury/heavy metal binding domains of minimally about 70 aas. It is found in MerP proteins (TC# 1.A.72) as N-terminal repeat copper binding domains in copper ATPases (TC# 3.A.3.5), in heavy metal binding domains (TC# 5.A.1.6), and in copper ion chaparone proteins (TC# 9.B.462).
