General information

Function Weakly binds calcium but binds zinc very tightly-distinct binding sites with

different affinities exist for both ions on each monomer. Physiological

concentrations of potassium ion antagonize the binding of both divalent cations,

especially affecting high-affinity calcium-binding sites.
