一般說明

辅酶 A (CoA) 是所有生物体普遍存在的一种辅助因子，通过半胱氨酸、泛酸（维生素 B5）和三磷酸腺苷 (ATP) 的酶促结合合成。

應用

辅酶 A 氧化锂盐已用于制备辅酶 A 过硫化物 (CoASSH) 标准品，以串联质谱法定量金黄色葡萄球菌菌株中的CoASSH。

生化／生理作用

辅酶 A (CoA) 在三羧酸循环和脂肪酸代谢等多种生化反应中充当酰基载体和羰基活化剂。它充当多种酶的辅助因子，参与多种中间代谢反应。CoA 含有硫醇基团，能够参与多种生化反应。氧化的CoA可用于研究在体内再生还原CoA的还原系统（CoA二硫键还原酶（CoADR）系统）。此外，氧化的CoA可用于研究该分子在体内的独特功能。

The time-dependent inactivation of hydroxymethylglutaryl-CoA reductase from yeast by solutions of hydroxymethylglutaryl-CoA and CoASH is due to the rapid inactivation of the enzyme by oxidized CoA (CoA disulfide) present at trace levels in solutions of hydroxymethylglutaryl-CoA and CoASH. Solutions of

The human pathogen Staphylococcus aureus does not utilize the glutathione thiol/disulfide redox system employed by eukaryotes and many bacteria. Instead, this organism produces CoA as its major low molecular weight thiol. We report the identification and purification of the disulfide

Physiologically significant levels of intracellular coenzyme A were identified in Pyrococcus furiosus, Thermococcus litoralis, and Sulfolobus solfataricus, suggesting a role for CoA as an important low molecular mass thiol in the thermophilic Archaea. In P. furiosus, cells grown in the

The cellular responses of Borrelia burgdorferiTo reactive oxygen species (ROS) encountered during the different stages of its infective cycle are poorly understood. Few enzymes responsible for protecting proteins, DNA/RNA and lipids from damage by ROS have been identified and characterized.
