Dioxygenases that open the aromatic ring in the vicinal position to the o-diols are called extradiol dioxygenases. A mononuclear Fe(II) or Mn(II) complex forms their active site. This is, for instance, the case of 2,3-dihydroxybiphenyl-1,2-dioxygenase of Pseudomonas sp. Strain KKS102, the square pyramidal geometry of which is schematized in Figure 3.3...

The initial hydroxylation of benzene, toluene, and other alkylbenzenes is accomplished by multicomponent aromatic ring dioxygenases that introduce two oxygen atoms to form diols.158 Dioxygenation of benzoate yields a diol that can be oxidatively decar-boxylated by reaction with NAD+ (Eq. 25-7) to form catechol.157,162 Toluene gives 3-methylcatechol... 

Dioxygenases which act on aromatic ortho-diphenols may either cleave the aromatic ring by an intradiol pathway or by an extradiol route, as shown in equation (77),...
