Highly Mesoporous Zr-Based MOF-Fabric Composites: A Benign Approach for Expeditious Degradation of Chemical Warfare Agents and Simulants. [PDF]
SmallThis research unveils a breakthrough in organophosphonate degradation using environmentally friendly mesoporous UiO–66–NH2‐fabric composites. This innovative approach, facilitated by CAPB surfactant, overcomes mass transfer limitations, creating robust, highly porous materials compatible with fragile fabrics.

Organophosphorus flame retardants in children’s car seats: Implications for vehicle air quality [PDF]
E3S Web of Conferences, 2023 Flame retardants (FRs) are used in many consumer products for fire safety reasons. Their use in children’s car seats may result in children’s and vehicle occupants’ exposure to these compounds including inhalation exposure through poor vehicle air ...

Genomic context analysis enables the discovery of an unusual NAD-dependent racemase in phosphonate catabolism. [PDF]
FEBS JThe authors identify PbfF (previously annotated as a NAD‐dependent dehydrogenase) as a hitherto unknown enzyme in phosphonate catabolism. Guided by genome context analysis, they show that PbfF is actually a racemase, serving to degrade the natural compound (S)‐2‐amino‐1‐hydroxyethylphosphonate (S‐HAEP).

Organophosphonate metabolism by a moderately halophilic bacterial isolate [PDF]
FEMS Microbiology Letters, 2000 A Gram-negative halophile isolated from soil beneath a road gritting salt pile grew optimally at 10% (w/v) NaCl and was shown most likely to be Chromohalobacter marismortui or Pseudomonas beijerinckii on the basis of 16S rRNA analysis. The strain utilised phosphonoacetate, 2-aminoethyl-, 3-aminopropyl-, 4-aminobutyl-, methyl- and ethyl-phosphonates as ...

Semiconductive microporous hydrogen-bonded organophosphonic acid frameworks [PDF]
Nature Communications, 2020 Abstract Herein, we report a semiconductive, proton-conductive, microporous hydrogen-bonded organic framework (HOF) derived from phenylphosphonic acid and 5,10,15,20‐tetrakis[ p ‐phenylphosphonic acid] porphyrin (GTUB5).

Structure of HI-6*sarin-acetylcholinesterase determined by X-ray crystallography and molecular dynamics simulation: reactivator mechanism and design. [PDF]
PLoS ONE, 2009 Organophosphonates such as isopropyl metylphosphonofluoridate (sarin) are extremely toxic as they phosphonylate the catalytic serine residue of acetylcholinesterase (AChE), an enzyme essential to humans and other species.

Catabolism and detoxification of 1-aminoalkylphosphonic acids: N-acetylation by the phnO gene product. [PDF]
PLoS ONE, 2012 In Escherichia coli uptake and catabolism of organophosphonates are governed by the phnCDEFGHIJKLMNOP operon. The phnO cistron is shown to encode aminoalkylphosphonate N-acetyltransferase, which utilizes acetylcoenzyme A as acetyl donor and ...

Novel Human Butyrylcholinesterase Variants: Toward Organophosphonate Detoxication [PDF]
Biochemistry, 2014 Human butyrylcholinesterase (hBChE) is currently being developed as a detoxication enzyme for stoichiometric binding and/or catalytic hydrolysis of organophosphates. Herein, we describe the use of a molecular evolution method to develop novel hBChE variants with increased resistance to stereochemically defined nerve agent model compounds of soman ...
