Genomic context analysis enables the discovery of an unusual NAD‐dependent racemase in phosphonate catabolism

The FEBS Journal, EarlyView.
The 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).

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 ...

New Wine in Old Bottles: Fully Substituted Arylthio Effect Realizes High‐Efficiency Purely Organic Phosphorescence Light‐Emitting Diode With Single and Ultra‐Stable Spectra Under 2000 cd m−2

Aggregate, Volume 6, Issue 4, April 2025.
Benefiting from the fully substituted arylthio effect, pure organic emitter 6S has the most obvious aggregation‐induced phosphorescence characteristic, the largest spin orbital coupling value, and the smallest the energy gap between S1 and T1. Consequently, a high maximum external quantum efficiency of 15.3% and ultra‐stable spectra under high ...

Discovery of a New, Recurrent Enzyme in Bacterial Phosphonate Degradation: (R)‑1-Hydroxy-2-aminoethylphosphonate Ammonia-lyase [PDF]

, 2021
Phosphonates represent an important source of bioavailable phosphorus in certain environments. Accordingly, many microorganisms (particularly marine bacteria) possess catabolic pathways to degrade these molecules. One example is the widespread hydrolytic
