应用
甲基丙二酰辅酶 A (CoA) 已用于超高效液相色谱-质谱法 (UPLC-MS/MS) 中校准曲线的制备。 也用于测定甲基丙二酰辅酶 a 变位酶和甲基丙二酰辅酶 a 差向异构酶活性。
辅酶 A 作为酰基载体，即乙酰辅酶 A 发挥作用。甲基丙二酰辅酶 A (MM-CoA) 是用于研究甲基丙二酰辅酶 A 变位酶（琥珀酰-Ca 形成）、甲基丙二酰辅酶 A 脱羧酶 (EC 4.1.1.41) 和甲基丙二酰辅酶 A 水解酶 (EC 3.1.2.17) 等酶的特异性和动力学的底物。
生化/生理作用
甲基丙二酰辅酶 A (CoA) 是单链脂肪酸、胆固醇和少量氨基酸（如缬氨酸、异亮氨酸、蛋氨酸、苏氨酸）的降解产物。 由丙酰辅酶 a 羧化酶 (PCC) 的活性产生。甲基丙二酰辅酶 A (CoA) 通过甲基丙二酰辅酶 A 变位酶 (MCM) 和维生素 B12 作为辅助因子转化为琥珀酰辅酶 A。低 MCM 活性或维生素 B12 代谢改变导致遗传代谢病甲基丙二酸血症 (MMA)。

Epimerase (Msed_0639) and mutase (Msed_0638 and Msed_2055) convert (S)-methylmalonyl-coenzyme A (CoA) to succinyl-CoA in the Metallosphaera sedula 3-hydroxypropionate/4-hydroxybutyrate cycle

The reported presence of a coenzyme B12-dependent methylmalonyl-CoA mutase in potatoes has been reexamined. The enzyme converting methylmalonyl-CoA was purified to electrophoretic homogeneity. Examination of the reaction product by 1H, 31P NMR and mass spectrometry revealed that it was methylmalonyl-3'-dephospho-CoA.

Coenzyme B(12) is used by two highly similar radical enzymes, which catalyze carbon skeleton rearrangements, methylmalonyl-CoA mutase and isobutyryl-CoA mutase (ICM). ICM catalyzes the reversible interconversion of isobutyryl-CoA and n-butyryl-CoA and exists as a heterotetramer. In this study, we have

Type I polyketide synthases (PKSs) are multidomain, multimodule enzymes capable of producing complex polyketide metabolites. These modules contain an acyltransferase (AT) domain, which selects acyl-CoA substrates to be incorporated into the metabolite scaffold. Herein, we reveal the sequences of three
