apoenzyme

the protein component of an enzyme that requires the presence of the prosthetic group (coenzyme) to form the functioning enzyme.

ap·o·en·zyme (apo),

(ap'ō-en'zīm),
The protein portion of an enzyme as contrasted with the nonprotein portion, coenzyme, or prosthetic portion (if present in the intact protein).

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).

apoenzyme

(ăp′ō-ĕn′zīm)
n.
The protein component of an enzyme, excluding additional components such as cofactors or inhibitors.

apoenzyme

[ap′ō·en′zīm]
Etymology: Gk, apo + en, into, zyme, ferment
the protein part of a holoenzyme. The nonprotein part is the prosthetic group, which is usually permanently attached to the apoenzyme.
