Genes and novel sRNAs involved in PAHs degradation in marine bacteria Rhodococcus sp. P14 revealed by the genome and transcriptome analysis.

ABSTRACT: Rhodococcus sp. P14 is able to degrade various polycyclic aromatic hydrocarbons (PAHs). In this study, 6 ring-hydroxylating dioxygenases and 24 monooxygenases genes related to PAHs degradation were identified in its genome. Moreover, various genes, like serine hydrolase, hydratase, alcohol dehydrogenase, protocatechuate 3,4-dioxygenase, β-ketoadipate CoA transferase and β-Ketoadipyl CoA thiolase, which were supposed to be involved in PAHs degradation were also identified. Based on the genome analysis, the proposed PAHs degradation pathway was constructed in P14 strain, which showed that PAHs was degraded into the acetyl CoA and succinyl CoA, then mineralized to CO₂ via the TCA cycle. Furthermore, several genes, including cytochrome P450 (RS16725; RS16695; RS12220), catala
