S. aureus cysM region and plasmids conferring tellurite resistance in E. coli. The inserts in pJIM27, pJIM28, pJIM29, and pJIM30 are shown in relation to the lac promoter on the pBK-CMV vector. The MIC of tellurite (MICT) of each clone is shown. The MIC of tellurite for E. coli DH5α is 1 μM. The inverted triangle shows the position of the tetracycline resistance cassette insertion in S. aureus J96 (cysM::tet). Plasmids pJIM80, used for complementation, and pJIM44, used to make S. aureus J62 (cysM-lacZ), are shown. ND, not determined.
