Myristoylcoenzyme A (myristoyl-CoA) is a derivative of CoA that contains the long-chain fatty acid myristic acid . It is a substrate for N-myristoyltransferase during myristoylation, a process that adds a myristoyl group to proteins either during translation to modify protein activity or post-translationally in apoptotic cells. It is also a substrate in the de novo synthesis of phosphatidylinositol .
Myristoylcoenzyme A lithium 为含锂标记的 Myristoylcoenzyme A (CoA),关键参与病毒生物学中N-肉豆蔻酰转移酶 (NMT) 控制的肉豆蔻酰化过程。NMT 在结肠上皮肿瘤细胞中相较正常细胞展现出更高的活性。已知,还原形态的 CoA 是调控 NMT 活性的主要因素,反之氧化态的 CoA 则抑制 NMT 促进的肉豆蔻酰化。因此,Myristoylcoenzyme A 表现出通过阻断肉豆蔻酰化过程的潜在抗癌和抗病毒作用。
