cofactor

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

没有辅助因子的叫做脱辅。

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

有一全是高度复杂的，如丙酮酸脱氢。

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

与脱辅基结合松弛、易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.

辅助因子两者结合成完整分子时，形成具有活力的全。

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

甲基丙二酸血症是由于甲基丙二酰辅A变位或其辅腺苷钴胺素缺陷所致的一种遗传性代谢疾病。
