| 1. | And, that image of the urease structure is purely decorative.
|
| 2. | For example, jack-bean urease has two structural and one catalytic subunit.
|
| 3. | The molecule is similar to urea but is not hydrolyzable by the urease enzyme.
|
| 4. | It produces a range of extracellular hydrolases including lipase, chitinase, and urease.
|
| 5. | The structure of urease was first solved by P . A . Karplus in 1995.
|
| 6. | Urease was the first ever enzyme crystallized.
|
| 7. | Environmental urease activity is often measured as an indicator of the health of microbial communities.
|
| 8. | The presence of urease is used in the diagnosis of " Helicobacter " species.
|
| 9. | One mechanism for the catalysis of this reaction by urease was proposed by Blakely and Zerner.
|
| 10. | The specimen should not be collected in tubes containing sodium fluoride because the fluoride inhibits urease.
