Compare with Definitions

Zymogen

A zymogen (), also called a proenzyme (), is an inactive precursor of an enzyme. A zymogen requires a biochemical change (such as a hydrolysis reaction revealing the active site, or changing the configuration to reveal the active site) for it to become an active enzyme.

Proenzyme

The inactive or nearly inactive precursor of an enzyme, converted into an active enzyme by proteolysis. Also called zymogen.

Zymogen

See proenzyme.

Proenzyme

(biochemistry) Any inactive precursor of an enzyme that is converted to an enzyme by proteolysis; a zymogen

Zymogen

(biochemistry) A proenzyme, or enzyme precursor, which requires a biochemical change (i.e. hydrolysis) to become an active form of the enzyme.

Proenzyme

Any one of a class of proteins that are converted, in the normal course of cellular metabolism, into one or more active enzymes; also called zymogen. The conversion usually is due to a specific cleavage of a peptide bond by another enzyme, or may be due to acid.

Zymogen

A mother substance, or antecedent, of an enzyme or chemical ferment; - applied to such substances as, not being themselves actual ferments, may by internal changes give rise to a ferment.
The pancreas contains but little ready-made ferment, though there is present in it a body, zymogen, which gives birth to the ferment.

Proenzyme

Any of a group of compounds that are inactive precursors of enzymes and require some change (such as the hydrolysis of a fragment that masks an active enzyme) to become active
