p aminobenzoic acid/arabidopsis

p-Aminobenzoic acid (pABA) plays important roles in a wide variety of metabolic processes. Herein we report the synthesis, theoretical calculations, crystallographic investigation, and in vitro determination of the biological activity and phytotoxicity of the pABA salt, 2-hydroxyethylammonium

Dihydropteroate synthase (DHPS) (EC 2.5.1.15) was extracted from leaves of Arabidopsis thaliana and purified 21-fold by ion-exchange chromatography. This enzyme preparation was then characterized for several of its properties. Michaelis-Menten constants for the substrates, p-aminobenzoic acid and

DNA methylation is a critical, dynamically regulated epigenetic mark. Small chemicals can be valuable tools in probing cellular processes, but the set of chemicals with broad effects on epigenetic regulation is very limited. Using the Arabidopsis thaliana repressor of silencing1 mutant, in which

On-site monitoring of volatile fatty acids (VFAs), such as propionate, is industrially and medically important. The present study developed a VFA biosensing system comprised of two recombinant enzymes, propionate coenzyme A (CoA) transferase (PCT) from Clostridium propionicum and acyl-CoA oxidase
