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].
