英文摘要 | Pseudomonas sp. strain nyz402 was isolated for its ability to grow on para-nitrophenol (pnp) as a sole source of carbon, nitrogen, and energy, and was shown to degrade pnp via an oxidization pathway. this strain was also capable of growing on hydroquinone or catechol. a 15, 818 bp dna fragment extending from a 800-bp dna fragment of hydroxyquinol 1,2-dioxygenase gene (pnpg) was obtained by genome walking. sequence analysis indicated that the pnp catabolic gene cluster (pnpabcdefg) in this fragment shared significant similarities with a recently reported gene cluster responsible for pnp degradation from pseudomonas sp. strain wbc-3. pnpa is pnp 4-monooxygenase converting pnp to hydroquinone via benzoquinone in the presence of nadph, and genetic analysis indicated that pnpa plays a key role in pnp degradation. pnpa1 present in the upstream of the cluster (absent in the cluster from strain wbc-3) encodes a protein sharing as high as 55% identity with pnpa, but was not involved in pnp degradation by either in vitro or in vivo analyses. furthermore, an engineered strain capable of growing on pnp and ortho-nitrophenol (onp) was constructed by introducing onpab (encoding onp monooxygenase and ortho-benzoquinone reductase which catalyzed the transformation of onp to catechol) from alcaligenes sp. strain nyz215 into strain nyz402. |
