u·re·ase

(yūr'ē-ās),
An enzyme that catalyzes the hydrolysis of urea to carbon dioxide and ammonia; used as an antitumor enzyme; it is present in intestinal bacteria and accounts for most of the ammonia generated from urea in mammals.

Nitrate upward (capillary rise) and downward (leaching) movements are higher when NBPT-treated urea is used, compared with conventional urea, which demonstrates greater mobility of the nitrate from urea treated with NBPT urease inhibitor and lower mobility of the nitrate from conventional urea.
In general, strong binding interactions of the ligand with protein complemented by good binding affinity expressed by binding energy propose this ligand as a possible candidate of urease inhibitor.
This indicated that BSW and SPAD at grain filling stage could reflect directly the changes of grain yield in different rates of urease inhibitors, it proved that rice yield of different amount of urease inhibitor could be estimated based on SPAD and BSW at grain filling stage with linear equation.
The results showed that sulfur and urease inhibitor (agrotain) coated urea significantly increased the dry matter yield, N uptake and grain quality of rice cultivars over granular urea (GU) and control treatment applied split, particularly in silty loam soil than clay loam soil.The N release was more pronounced in silty loam (SL) soil as compared to clay loam (CL) soil where, the effect of the inhibitors was less evident.
Urease inhibitors are expected to be most beneficial on soils where loss of ammonia from application of urea fertiliser is high.
Another urease inhibitor, phenyl phosphorodiamidate (PPDA), produced similar results.
"The enzyme's structure is important biomedically because urease inhibitors may be able to stop these invasive bacteria," he says.

Some techniques maximize the efficiency of N fertilization (Zhang et al., 2015), especially the addition of urease inhibitors such as N-(n-butyl)thiophosphoric triamide (NBPT) and the coating of N fertilizers with polymers, resins and gypsum (Sanz-Cobena et al., 2012; Halvorson et al., 2014).
