Abstract
1. One Cd-binding peak was detected after gel filtration chromatography on Sephadex G75 in an extract from Allolobophora caliginosa contaminated with Cd. 2. Two subsequent cation-exchange chromatographies allowed the isolation of a Cd-binding protein which was called Cd-BP14. This protein is a monomer with a molecular weight of 14 kDa and has an isoelectric point of 6.5. 3. Amino acid analysis showed the presence of a high level of aromatic amino acids and a lack of cysteine. 4. On the basis of these results we conclude that Cd-BP14 is different from metallothioneins described in mammals or other invertebrates.
