General description

Urease is a nickel-containing enzyme found in plants, bacteria, fungi, algae, and soil. It is a hexamer of a single chain of 840 amino acid residues. Urease is localized to mature seeds.

Biochem/physiol Actions

Ureases are metalloenzymes that catalyze the hydrolysis of urea to release ammonia (a nitrogen source for growth) and carbon dioxide. In plants, ureases are essential for the bioavailability/metabolism of nitrogen in nature and defense mechanisms. They exhibit internal peptides-mediated insecticidal action and fungicidal activity.
