cofactor

1.An enzyme without its cofactor is termed an apoenzyme.

没有辅助因子的酶叫做脱辅酶。

2.Some holoenzymes, such as pyruvate dehydrogenase, are highly compex, with several cofactors.

有一全酶是高度复杂的，如丙酮脱氢酶。

3.A cofactor bound loosely to the apoenzyme and readily separable from it is a coenzyme.

与脱辅基蛋白结合、于与之分离的辅基因子称为辅。

4.When a catalytically active enzyme forms a complex with a cofactor a holoenzyme is produced.

酶蛋白和辅助因子两者结合成完整分子时，形成具有活力的全酶。

5.Methylmalonic acidemia is an inherited metabolic disorder,which is caused by deficiency of methylmalonyl-coenzyme A mutase or its cofactor adenosylcobalamin.

甲基丙二血症是由于甲基丙二酰辅酶A变位酶或其辅酶腺钴胺素缺陷所致的一种遗传性代谢疾病。
