We therefore developed a rigorous method to purify MDA produced in a reaction catalyzed by an equine alcohol dehydrogenase (ADH; 28). The labeled MDA was purified on an anion exchange resin, fed as a volatile to plants, and traced to lipid pools by mass spectrometry. A major isotope-labeled...
With the aim of combining a gene switch with an abiotic reaction catalyzed by an ArM in a designer mammalian cell, we combined a ruthenium catalyst for the intracellularO-allyl carbamate cleavage12,14,19,35with a gene switch that is upregulated in the presence of the thyroid hormone, triiodot...
The major route for PFAM degradation in vivo is the hydrolysis to fatty acid and ammonia, a reaction catalyzed by fatty acid amide hydrolase (FAAH) (31, 32). Less is definitively known about PFAM biosynthesis. One proposed route is the ammonolysis of fatty acyl-CoA thioesters (33), whereas...

The time courses of the hydrolysis reaction catalyzed by PnGH1 were evaluated at different time points of 5 min–48 h. All experiments were performed in triplicate. To determine the kinetic values (KM, kcat, and kcat/KM) of PnGH1 towards Rb3, reactions were performed in a total volume ...

These two genes belong to the same operon [12] and are constitutively expressed, although ackA is slightly activated by Fnr [13]. The reaction catalyzed by these two enzymes generates an unstable intermediate, acetyl-phosphate (Figure 1), which phosphorylates proteins related to signal transduction...
