Application

Coenzyme A hydrate has been used in the thiolase enzyme assay of recombinant acetoacetyl-CoA thiolase (rACAT) in Clonorchis sinensis. It may be used as a reference standard in Raman spectra measurements.

Biochem/physiol Actions

Coenzyme A (CoA) is an essential metabolic cofactor synthesized from cysteine, pantothenate, and ATP. CoA plays important roles in many metabolic pathways, including the tricarboxylic acid cycle, and the synthesis and oxidation of fatty acids. One of the main functions of CoA is the carrying and transfer of acyl groups. Acylated deriviates, for example acetyl-CoA, are critical intermediates in many metabolic reactions. CoA levels can be altered during starvation, and in conditions such as cancer, diabetes, and alcoholism.

Caution

The free acid is less stable than the sodium or lithium salt; 5% decomposition may occur within 6 months when stored at −80 °C.

Active metabolism regulates oocyte cell death via calcium/calmodulin-dependent protein kinase II (CaMKII)-mediated phosphorylation of caspase-2, but the link between metabolic activity and CaMKII is poorly understood. Here we identify coenzyme A (CoA) as the key metabolic signal that inhibits Xenopus

We have previously reported that the majority of the archaea utilize a novel pathway for coenzyme A biosynthesis (CoA). Bacteria/eukaryotes commonly use pantothenate synthetase and pantothenate kinase to convert pantoate to 4'-phosphopantothenate. However, in the hyperthermophilic archaeon Thermococcus kodakarensis, two

Alterations in mitochondrial protein acetylation are implicated in the pathophysiology of diabetes, the metabolic syndrome, mitochondrial disorders, and cancer. However, a viable mechanism responsible for the widespread acetylation in mitochondria remains unknown. Here, we demonstrate that the physiologic pH and

The sirtuins are a family of NAD(+)-dependent protein deacetylases that regulate cell survival, metabolism, and longevity. Three sirtuins, SIRT3-5, localize to mitochondria. Expression of SIRT3 is selectively activated during fasting and calorie restriction. SIRT3 regulates the acetylation level and enzymatic
