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

有一些全度复杂的，如丙酮酸氢。

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

蛋白和辅助因两者结合成完整分时，形成具有活力的全。

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

辅基蛋白结合松弛、易于之分离的辅基因称为辅。

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