PNP degradation pathway and the two general pathways via hydroquinone or hydroxyquinol. PNP4O: p-nitrophenol 4-monooxygenase, (1.14.13.-); BQR: p-benzoquinone reductase, (1.6.5.-); H1,2O: hydroquinone 1,2-dioxygenase, (1.13.11.-); 4HSD: γ-hydroxymuconic semialdehyde dehydrogenase, (1.2.1.61); MAR: maleylacetate reductase, (1.3.1.32); N4O: 4-nitrocatechol 4-monooxygenase, (1.14.-); PNP2O: p-nitrophenol 2-monooxygenase, (1.14.13.29); QR: 2-hydroxy-1,4-benzoquinone reductase, (1.14.-); 1,2,4BTO: 1,2,4-benzenetriol dioxygenase, (1.13.11.37). The red arrows show enzyme actions designed for engineered strain, the dotted arrows show spontaneous reactions in bacteria
