An enzyme without its cofactor is termed an apoenzyme.

没有助子的叫做脱。

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

有一是高度复杂的，如丙酮酸脱氢。

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

与脱基蛋白结松弛、易于与之分离的基子称为。

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

蛋白和助子两者结成完整分子时，形成具有活力的。

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A变位或其腺苷钴胺素缺陷所致的一种遗传性代谢疾病。
