  • The pcaH was significant in the β-ketoadipate pathway [9] where the pathway as it conserves biochemically, and is a major class of non-heme-iron containing dioxygenase [ 10 ]. (omicsonline.org)
  • Moreover, a dioxygenase gene, nidA3B3, was detected in Mycobacterium vanbaalenii PYR-1 as an alternate degradation pathway which could catalyze both the initial dihydroxylation of pyrene [ 11 ] to be pyrene cis-4,5-dihydrodiol, and an alternate detoxification pyrene pathway to be pyrene cis-1,2-dihydrodiol [ 12 ].
