TMCd1 is made up of 156 amino acids, of which 47 are cysteine 2+ residues that can bind 16 Cd.

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.
