Microbial Degradation of Some Halogenated Compounds: Biochemical and Molecular Features
Due to the advance of organic and synthetic chemistry and many applications of man-made organic compounds, lots of xenobiotic chemicals are produced and benefit our life. However, some of them are persistent in the environment and their toxicities are accumulated through the food webs. Due to the potential hazard for human and the ecosystem, the regulations on the usage of these persistent orga...

متن کاملMechanism of action of toxic halogenated aromatics.
2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) and related halogenated aromatic hydrocarbons are a highly toxic class of environmental contaminants, as evidenced by numerous cases of accidental poisonings of human and animal populations and their extreme toxic potency in laboratory animals. The proposed model for the mechanism of action of TCDD and related compounds is analogous to that of the ster...

متن کاملMechanisms and free energies of enzymatic reactions.
Most enzymatic reactions have very large and remarkably similar apparent second-order rate constants, kcat/KM, at mean values of about 107 M-1 s-1 with kcat in the range of 101000 s-1.1-3 In fact, many reactions approach the diffusional encounter rate at the limited enzyme concentration (<10-5 M) in the cell.4 Wolfenden illustrated the catalytic power of enzymes by comparing the rate constant o...
