A zinc-binding protein in a metal-resistant strain, Alcaligenes eutrophus CH34.

Synthesis of a zinc-binding protein was induced when Alcaligenes eutrophus CH34 was grown in the presence of high concentrations of zinc (2.3 mM). The zinc-binding protein has a low content of cysteine and a high content of acidic amino acids and, thus, differs from metallothionein.
