CzcB is a crucial component of the CzcCBA protein complex, which mediates heavy metal resistance in bacteria through an active cation efflux mechanism [1]. CzcB binds to CzcA, which in turn is bound to CzcC, forming the complete CzcCBA complex. The domain represented by this entry folds into an open barrel with a circularly permuted topology of SH3-like barrels.

PF19335Heavy metal binding domain (HMBD)Heavy metal binding domainThis domain is a copper-binding domain found in single or multiple copies at the N-terminus of a wide variety of copper or other heavy metal binding transporters and other proteins. In the Ag+/Cu+- binding domains of the periplasmic adaptor protein S ...This domain is a copper-binding domain found in single or multiple copies at the N-terminus of a wide variety of copper or other heavy metal binding transporters and other proteins. In the Ag+/Cu+- binding domains of the periplasmic adaptor protein Silb, three conserved methionine residues located between the tip of the short beta-sheet and a loop, forming a sort of clamp, bind the Ag+ ion [5].
