الوصف: The organophosphate degrading (opd) gene cluster of plasmid pPDL2 of Flavobacterium sp. ATCC27551 contains a novel open-reading frame, orf243. This was predicted to encode an alpha/beta hydrolase distantly related to the meta-fission product (MFP) hydrolases such as XylF, PhnD, and CumD. By homology modeling Orf243 has most of the structural features of MFP hydrolases including the characteristic active site catalytic triad. The purified protein (designated MfhA) is a homotetramer and shows similar affinity for 2-hydroxy-6-oxohepta-2,4-dienoate (HOHD), 2-hydroxymuconic semialdehyde (HMSA), and 2-hydroxy-5-methylmuconic semialdehyde (HMMSA), the meta-fission products of 3-methyl catechol, catechol, and 4-methyl catechol. The unique catalytic properties of MfhA and the presence near its structural gene of cis-elements required for transposition suggest that mfhA has evolved towards encoding a common hydrolase that can act on meta-fission products containing either aldehyde or ketone groups.

الوصف: Several bacterial strains that can use organophosphate pesticides as a source of carbon have been isolated from soil samples collected from diverse geographical regions. All these organisms synthesize an enzyme called parathion hydrolase, and in each case the enzyme is encoded by a gene ( opd ) located on a large indigenous plasmid. These plasmids show considerable genetic diversity, but the region containing the opd gene is highly conserved. Two opd plasmids, pPDL2 from Flavobacterium sp. and pCMS1 from Pseudomonas diminuta , are well characterized, and in each of them a region of about 5.1 kb containing the opd gene shows an identical restriction pattern. We now report the complete sequence of the conserved region of plasmid pPDL2. The opd gene is flanked upstream by an insertion sequence, ISFlsp 1 , that is a member of the IS 21 family, and downstream by a Tn 3 -like element encoding a transposase and a resolvase. Adjacent to opd but transcribed in the opposite direction is an open reading frame ( orf243 ) with the potential to encode an aromatic hydrolase somewhat similar to Pseudomonas putida TodF. We have shown that orf243 encodes a polypeptide of 27 kDa, which plays a role in the degradation of p -nitrophenol and is likely to act in concert with opd in the degradation of parathion. The linkage of opd and orf243 , the organization of the genes flanking opd , and the wide geographical distribution of these genes suggest that this DNA sequence may constitute a complex catabolic transposon.
