title: Cadmium-binding component in Escherichia coli during accommodation to low levels of this ion.
abstract: An inducible cadmium-binding protein was isolated from Escherichia coli cells accommodated to 3 X 10(-6) M Cd2+ but not from normal or unaccommodated cells. Sephadex G-100, metal chelate affinity chromatography, and disc gel electrophoresis were used in the purification procedure. The molecular weight of the Cd2+-binding protein was estimated to be about 39,000 by Sephadex G-100 chromatography, making it different from the conventional, much smaller metallothionein.
