ZinT plays a critical role in recruiting periplasmic zinc to the bacterial zinc-uptake complex ZnuABC, consisting of families Pfam:PF01297,Pfam:PF00950, Pfam:PF00005, regulated by the transcription-regulator FUR, Pfam:PF01475 [2,3]. ZinT acts as a Zn2+-buffering protein that delivers Zn2+ to ZnuA (TroA), Pfam:PF01297 [4]. Members of this family of prokaryotic domains were first identified as part of the response of bacteria to a challenge with the toxic heavy metal cadmium. They are able to bind to cadmium, and ensure its subsequent elimination [1].	Domain
