Nitro groups are often associated with synthetically manufactured compounds such as medicines and explosives, rarely natural products. Loquat emits a nitro compound, (2-nitroethyl)benzene, flower scent. The compound exhibits fungistatic activity is biosynthesised from l-phenylalanine via (E/Z)-phenylacetaldoxime. Although aldoxime-producing CYP79s have been intensively studied, it unclear what ...
Aldoxime dehydratase (OxdA), which is a unique heme protein, catalyzes the dehydration of an aldoxime to a nitrile even in the presence of water in the reaction mixture. Unlike the utilization of H(2)O(2) or O(2) as a mediator of catalysis by other heme-containing enzymes (e.g., P450), OxdA is notable for the direct binding of a substrate to the heme iron. Here, we determined the crystal struct...
Reactivation of diethyl p-nitrophenyl phosphate inhibited human serum cholinesterase by pyridine-Z-aldoxime methiodide and isonitrosoacetophenone has been investigated as a function of reactivator concentration, pH, and temperature in boric acid-borax buffer and in salt solution. Constants shown were the dissociation constants of the diethylphosphoryl cholinesterase reactivator complex for the ...
Z-phenylacetaldoxime (Z-PAOx) degrading bacterium, identified as Bacillus sp. strain OxB-1, was isolated from soil after 2 months acclimation. The enzyme involved in the degradation of Z-PAOx was induced by the aldoxime and required FMN for its activity. The enzyme was partially purified from the cell-free extract of the strain and shown to catalyze the stoichiometric dehydration reaction of Z-...
