A core enzyme consists of the subunits of an enzyme that are needed for catalytic activity, as in the core enzyme RNA polymerase.
An example of a core enzyme is a RNA polymerase enzyme without the sigma factor (σ). This enzyme consists of only two alpha (2α), one beta (β) and one beta prime (β'). This is just one example of a core enzyme. DNA Pol I can also be characterized as having core and holoenzyme segments, where the 5'exonuclease can be removed without destroying enzyme functionality.
Famous quotes containing the word core:
“Avoiding humiliation is the core of tragedy and comedy.”
—John Guare (b. 1938)
