Polymerase chain reaction for identification of aldoxime dehydratase in aldoxime- or nitrile-degrading microorganisms.
We developed a molecular screening procedure using Southern hybridization and polymerase chain reaction (PCR) to identify aldoxime dehydratase (Oxd) encoding genes (oxds) among 14 aldoxime- or nitrile-degrading microorganisms. When an oxd gene of Rhodococcus erythropolis N-771 was used as a probe, positive hybridization signals were seen with the chromosomal DNA of eight strains, suggesting tha...
متن کاملBis(acetato-κO)bis(pyridine-2-aldoxime-κ2 N,N′)nickel(II)
In the mononuclear title compound, [Ni(CH(3)COO)(2)(C(6)H(6)N(2)O)(2)], the Ni(II) atom is coordinated by two pyridine-2-aldoxime (PaoH) ligands and two acetate groups, with cis coordination for the pairs of identical ligands. While each acetate group binds to the Ni(II) atom by one O atom, each PaoH chelates the Ni(II) atom through two N atoms. The O atom on PaoH is not deprotonated and does n...
متن کاملDistribution of aldoxime dehydratase in microorganisms.
The distribution of phenylacetaldoxime-degrading and pyridine-3-aldoxime-degrading ability was examined with intact cells of 975 microorganisms, including 45 genera of bacteria, 11 genera of actinomyces, 22 genera of yeasts, and 37 genera of fungi, by monitoring the decrease of the aldoximes by high-pressure liquid chromatography. The abilities were found to be widely distributed in bacteria, a...
متن کاملA one-pot synthesis of 3-trifluoromethyl-2-isoxazolines from trifluoromethyl aldoxime
Functionalized 3-trifluoromethyl-2-isoxazolines and 3-trifluoromethylisoxazoles were easily prepared from trifluoromethyl aldoxime 2 under mild conditions by using DIB as oxidant. Theoretical studies of the reactivity of trifluoroacetonitrile oxide 4 toward olefins and alkynes were carried out. The 3-trifluoromethyl-2-isoxazolines were ring-opened with NaBH4 and NiCl2 to yield the corresponding...
متن کاملRegulation of aldoxime dehydratase activity by redox-dependent change in the coordination structure of the aldoxime-heme complex.
Phenylacetaldoxime dehydratase from Bacillus sp. strain OxB-1 (OxdB) catalyzes the dehydration of Z-phenylacetaldoxime (PAOx) to produce phenylacetonitrile. OxdB contains a protoheme that works as the active center of the dehydration reaction. The enzymatic activity of ferrous OxdB was 1150-fold higher than that of ferric OxdB, indicating that the ferrous heme was the active state in OxdB catal...
