‘Taro-like’ odor is an important economic trait of pumpkin species. The metabolic and molecular bases this aromatic remain largely unexplored. Therefore, in study, gas chromatography-mass spectrometry, GC-Olfactometry, RNA-seq technology were used to illuminate the differential volatile compounds, key differentially expressed genes (DEGs) leaves from two samples. Eight including (E)-2-nonenal, ...
A cytosolic sialic acid-specific O-acetyl-esterase was previously described that can remove O-acetyl esters from the 9-position of sialic acids. We show that rat liver Golgi vesicles contain a distinct sialic acid-esterase located within the lumen of the same vesicles that add O-acetyl esters to sialic acids. Studies of a retinoblastoma cell line genetically deficient in the cytosolic enzyme al...
Several bacterial response regulator proteins (CheY, NRI, PhoB, and OmpR) become phosphorylated in vitro when incubated with acetyl phosphate. In the presence of high levels of acetyl phosphate and Mg2+, CheY reached steady state phosphorylation in less than 30 s; NRI and PhoB reached steady state more slowly (t1/2 to steady state of 1.5 and > 15 min, respectively). A simple method was develope...
As a key intracellular metabolite, acetyl-coenzyme A (acetyl-CoA) plays a major role in various metabolic pathways that link anabolism and catabolism. In the yeast Saccharomyces cerevisiae, acetyl-CoA involving metabolism is compartmentalized, and may vary with the nutrient supply of a cell. Membranes separating intracellular compartments are impermeable to acetyl-CoA and no direct transport be...
Abstract [2.2]Paracyclophane (PCP) derivatives have been promising platforms to study the element of planar chirality and through‐space electronic communications in π‐stacked molecular systems. To access enantiomerically pure thereof, a kinetic resolution 4‐acetyl[2.2]‐PCP employing ruthenium‐catalyzed enantioselective hydrogenation process was developed. This method can be performed on multigr...
UNLABELLED Syntrophus aciditrophicus is a model syntrophic bacterium that degrades key intermediates in anaerobic decomposition, such as benzoate, cyclohexane-1-carboxylate, and certain fatty acids, to acetate when grown with hydrogen-/formate-consuming microorganisms. ATP formation coupled to acetate production is the main source for energy conservation by S. aciditrophicus However, the absenc...
BACKGROUND Acetyl-CoA is an important precursor in Saccharomyces cerevisiae. Various approaches have been adopted to improve its cytosolic level previously with the emphasis on engineering the "acetyl-" part of acetyl-CoA. To the best of our knowledge, there have been no reports on engineering the "-CoA" part so far. RESULTS In this study, we had tried to engineer S. cerevisiae from both the ...
Previous studies of the choline acetylation system of brain and of the head ganglion of the squid have utilized acetate, ATP,’ and CoA to generate “active acetate” (1, 2). Following the isolation of acetyl CoA by Lynen et al. (3), its identity with “active acetate” has been established by the demonstration that the acetylated coenzyme is the acetyl donor in the biological acetylation of sulfani...
