Abstract

PCBs Degradation of the Enzyme and its Dynamics

Highlights

  • Polychlorinated biphenyls (PCB) are one of the most polluted compounds

  • In most PCB-degrading bacteria, biphenyl rely on a series of enzymes: such as biphenyl dioxygenase (BphA), dihydro-dihydroxybiphenyl dehydrogenase (BphB), 2,3-dihydroxy-biphenyl-dioxygenase (BphC) and biphenyl hydrolase (BphD), transformed into benzoic acid and 2-hydroxy-pentyl 2,4-dienoic acid. 2,3-the biphenyl dioxygenase catalyzed biphenyl ring adjacent to ortho and meta-positioned carbon atoms to produce 2,3-dihydro-2,3-dihydroxy biphenyl

  • Dihydrodihydroxy intermediate via a dependent NAD+ dehydrogenase transformed to generate 2,3-dihydroxybiphenyl (DHBP), ring splitting enzyme-catalyzed ring-opening formation of benzoic acid and amyl final BphD spray fracture, 4 - dienoic acid
