应用
3′-脱磷酸辅酶 A 已被用作启动转录的底物。
脱磷酸辅酶 A 是辅酶 A 的直接前体。通过双功能 CoA 合成酶（CoASy,4′-磷酸泛素腺苷基转移酶/去磷酸-CoA 激酶），其负责 γ-干扰素的转移-ATP 的磷酸盐转化为去磷酸辅酶 A。
生化/生理作用
3′-脱磷酸辅酶 A (DepCoA) , 也称为脱磷酸辅酶 A (dpCoA) , 是由 4-磷酸泛酰乙胺通过磷酸泛酰乙胺腺苷基转移酶合成。是辅酶 A 生物合成途径中的一种中间体。在去磷酸 CoA 激酶 (CoaE) 存在下，去磷酸辅酶 A 转化为辅酶 A。3′-脱磷酸辅酶与嘌呤类一样共享腺苷二磷酸亚结构，是一种非经典核苷酸，是转录起始的启动因子。在 体外 转录研究中常规用于启动 RNA 合成。

4-Chlorobenzoyl-coenzyme A (4-CBA-CoA) dehalogenase catalyzes the hydrolytic dehalogenation of 4-CBA-CoA to 4-hydroxybenzoyl-CoA (4-HBA-CoA) via a multistep mechanism involving initial attack of Asp145 on C(4) of the substrate benzoyl ring to form a Meisenheimer intermediate (EMc), followed by expulsion of the

Phosphopantetheine adenylyltransferase (PPAT) catalyzes the penultimate step in coenzyme A (CoA) biosynthesis: the reversible adenylation of 4'-phosphopantetheine yielding 3'-dephospho-CoA and pyrophosphate. Wild-type PPAT from Escherichia coli was purified to homogeneity. N-terminal sequence analysis revealed that the enzyme is encoded by
