Protein Family Models

This is a metal-binding protein which is involved in resistance to heavy-metal ions [1,2]. The protein forms a four-helix hooked hairpin, consisting of two long alpha helices each flanked by a shorter alpha helix. It binds a metal ion in a type-2 like centre [3]. It contains two copies of an LTXXQ motif. [1]. 9694902.
