Abstract

By inactivation of different concentrations of 3-methylcrotonyl-CoA carboxylase from Achromobacter IVS with a fixed concentration of iodoacetamide, it was demonstrated that the degree of dissociation of the complex is considerably lower in the presence of 3-methylcrotonyl-CoA. ATP did not produce this effect. This property could serve to regulate the intracellular degradation of the enzyme, if the dissociated subunits were attacked preferentially.

摘要

通过用固定浓度的碘乙酰胺使来自无色杆菌IVS的不同浓度的3-甲基巴豆酰辅酶A羧化酶失活，结果表明在3-甲基巴豆酰辅酶A存在下复合物的解离程度显著降低。ATP没有产生这种效果。如果解离的亚基被优先攻击，这种特性可用于调节该酶在细胞内的降解。
