Six Major Classes of Enzymes and Examples of Their Subclasses
... Some enzymes associate with a nonprotein cofactor that is needed for enzymic activity. Commonly encountered cofactors include metal ions (for example, Zn2+, Fe2+) and organic molecules, known as coenzymes, that are often derivatives of vitamins (for example, NAD+, FAD, coenzyme A. Holoenzyme refers ...
