描述

一般說明

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.

生化／生理作用

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.
