TMCd1
TMCd1 has a strong cadmium absorbing ability. It's absorption capacity of recombinant strain to Cd increased to 7. 90 μ mol/mg dry cell weight, which was nearly 19 times higher than that of the control strain. TMCd1 is made up of 156 amino acids, of which 47 are cysteine 2+ residues that can bind 16 Cd. Therefore, Suleman et al. expressed the TMCd1 gene fused to the glutathione S-transferase gene in E. coli BL21 DE3 cells. We used it in the cytoplasm to chelate the cadmium ions inhaled from the cytosol of E. coli.

Summary: We have successfully expressed TMCd1 in E. coli DH5α(Figure1 a). The OD600 of E.coli expressed by TMCd1 represents that the concentration of bacteria, will increase faster than that without expression（Figure1. b).
