RESUMO
In a search for genes that produce hypersensitivity to cadmium salts in Escherichia coli, random transposon mutagenesis with TnphoA was used. One of the mutant strains obtained was sensitive to Cd2+ and Zn2+. Sequence analysis showed that the TnphoA insertion was located in the dsbA gene coding for a periplasmic protein required for disulfide bond formation.
