apoenzyme

/apo·en·zyme/ (ap″o-en´zīm) the protein component of an enzyme separable from the prosthetic group (coenzyme) but requiring the presence of the prosthetic group to form the functioning compound (holoenzyme).

Alternatively, MT can donate Zn to apoenzymes and transcription factors [16][17] and may thus serve as a labile source of Zn that can be utilized in many different organs to activate as-yet-unidentified metalloenzymes that are essential during the stress condition.
