Human liver aldehyde dehydrogenase was inhibited by aromatic chelating agents. However, structurally related compounds with much lower metal-complexing ability displayed affinities for enzyme essentially equal to those of their respective chelating analogues. Inhibition was competitive with respect to the coenzyme. It is suggested that hydrophobic interactions between the inhibitors and the coenzyme-binding site of the enzyme are responsible for the observed effects on activity.
人肝脏醛脱氢酶受到芳香族螯合剂的抑制。然而,具有低得多的金属络合能力的结构相关化合物对该酶的亲和力基本上与其各自的螯合类似物相同。抑制作用相对于辅酶而言是竞争性的。有人提出,抑制剂与酶的辅酶结合位点之间的疏水相互作用是观察到的对活性产生影响的原因。
