MntH

It expressed it on Bacillus thuringiensis using it to take up cadmium ions. Bacillus subtilis also belongs to the NRAMP family, which is a proton-coupled metal ion transporter.We use it to transport Cd ion into synechocystis.

Summary: We have successfully expressed MntH in E. coli DH5α(Figure1 a). The OD600 of E.coli expressing MntH ,which represents that the concentration of E. coli, will increase lower than that without expression（Figure1. b). It may be due to the transport of cadmium ions into cells leading to cell death. At the same time, When cadmium concentrations rise, it is more likely to die（Figure1. d), But it showes a very strong ability to absorb cadmium.（Figure1. e）
