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).

Green Highly Porous Bio‐Zr‐MOF/Fabric Composites for Organophosphonates Detoxification
Chemical Engineering and TechnologyDiscover a sustainable solution for tackling toxic organophosphates. Using bio‐based linkers and water as a solvent, we synthesize eco‐friendly Zr‐fumarate and MIP‐202 composites on fabric, achieving enhanced degradation rates. These composites outperform traditional MOFs like UiO‐66‐NH2, rapidly breaking down harmful chemicals, with applications in ...

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 ...
