cofactor

An enzyme without its cofactor is termed an apoenzyme.

没有辅助因子的叫做脱辅。

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

有高度复杂的，如丙酮酸脱氢。

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

与脱辅基蛋白结合松弛、易于与之分离的辅基因子称为辅。

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

蛋白和辅助因子两者结合成完整分子时，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.
