Term

transition metal ion binding

ID (Ontology)

GO:0046914 (Gene Ontology)

Definition

Binding to a transition metal ions; a transition metal is an element whose atom has an incomplete d-subshell of extranuclear electrons, or which gives rise to a cation or cations with an incomplete d-subshell. Transition metals often have more than one valency state. Biologically relevant transition metals include vanadium, manganese, iron, copper, cobalt, nickel, molybdenum and silver.[ ISBN:0198506732 ]
