Abstract
We have isolated 14 cadmium (Cd)-resistant, soil-borne bacteria. Among those, strain CT14, which was identified as an Alcatigenes sp., has a czc (cadmium, zinc, and cobalt divalent cation resistant determinant) system. Here we report the nucleotide sequence of 4 genes (czcCBAD) of the system. CzcCBA showed over 98% identity with those of A. eutrophus CH34, however, CzcD, the distal gene product, was 117 amino acids longer than that (199 amino acids) of A. eutrophus CH34, and had considerable similarity to the members of the CDF (cation diffusion facilitator) family proteins all over the region.
