Apoferment
Definition
The proteinaceous, macromolecular, and thermolabile component of a conjugated enzyme, which determines its action specificity toward a specific substrate; a constituent part of a holoenzyme. To become catalytically active, this pure protein structure requires mandatory coupling with a non-protein component called a coenzyme or cofactor.
