Recently, we discovered an intriguing hemoprotein [aliphatic aldoxime dehydratase (OxdA)] that catalyzes the dehydration of aliphatic aldoximes [R-CH=N-OH] to the corresponding nitriles [R-C identical withN] in the industrial Pseudomonas chlororaphis B23 strain. Unlike the utilization of H(2)O(2) or O(2) as a mediator of the catalysis by other heme-containing enzymes (e.g., P450), OxdA is notab...

The employment of 3-pyridine aldoxime, (3-py)CHNOH, in Zn(II) chemistry has afforded two novel compounds: [Zn(acac)(2){(3-py)CHNOH}]·H(2)O (1·H(2)O) [where acac(-) is the pentane-2,4-dionato(-1) ion] and [Zn(2)(O(2)CMe)(4){(3-py)CHNOH}(2)] (2). Complex 1·H(2)O crystallizes in the monoclinic space group P2(1)/n. The Zn(II) ion is five-coordinated, surrounded by four oxygen atoms of two acac(-) m...

We report the synthesis of new polymers based on a dimethylacrylamide-methacrylate (DMAA-MA) co-polymer backbone that support both chemical and biological agent decontamination. Polyurethanes containing the redox enzymes glucose oxidase and horseradish peroxidase can convert halide ions into active halogens and exert striking bactericidal activity against gram positive and gram negative bacteri...
