Microbe-catalyzed transformation

The growth in the studies of nomnammalian cytochrome P450 systems, particularly those of plants and microbes, has unearthed a rich and nnforeseen complexity of cytochrome P450-catalyzed transformations. The breadth of cytochrome P450 catalysis will snrely continue to grow as these still relatively imexplored biological domains reveal the diversity of aims to which... 

A number of instances can be cited from the literature wherein the isosteres had similar transformations. Bacterial dioxygenase-catalyzed ci5-dihydroxylation of the tetracyclic arene benzo[c]phenanthrene was found to occur exclusively at fjord region (cavity region) bonds. The isosteric compounds benzo[b]naphthol [l,2-d]furan and benzo[b]naphthol[l,2-d]thiophene were also similarly ci5-dihydroxylated at the fjord region bonds by bacterial dioxygenases (Boyd et al., 2001) (see Fig. 4.3). The isosteres 1,2-dihydronaphthalene, 2,3-dihydrobenzothiophene, and 2,3-dihydro-benzofuran gave similar corresponding diol products on incubation with Pseudomonas putida UV4. Microbes that possess the metabolic pathways to metabolize benzene, when substituted by...
