Proteomic Characterization of Plasmid pLA1 for Biodegradation of Polycyclic Aromatic Hydrocarbons in the Marine Bacterium, Novosphingobium pentaromativorans US6-1
Figure 3
Two extradiol biodegradation pathways of N. pentaromativorans US6-1.
Two biodegradation pathways were identified by genomic analysis using KEGG program and the induced enzymes were confirmed by proteomic analysis of N. pentaromativorans US6-1. PAHs are assumed to converge into 1,2-dihydroxynapthalene, whereas, ring-hydroxylating dioxygenase and dihydrodiol dehydrogenase are induced in our PAHs culture conditions. Up: Catechol 2,3-dioxygenase pathway (large plasmid pLA1). Down: Protocatechuate 4,5-dioxygenase pathway (chromosome).
