title: [Genes of metal-binding proteins and their application in bioremediation of heavy metals].
abstract: Heavy metal pollution has become a global environmental hazard. The use of microorganisms and plants for the decontamination of heavy metals is recognized as a low lost and high efficiency method for cleaning up metal contamination. It shows that various metal-binding proteins such as metallothioneins (MTs) or phytochelatines (PCs) play an important role in defense systems and detoxification to heavy metals in organisms. Many genes of MTs and PCs have been cloned and utilized successfully in genetically modified bacteria and plants for increasing remediation capacity. These transgenic organisms have been displayed a great potential in bioremediation and phytoremediation of heavy metals.
