| 1. | It is characterized by lowered activity of arginase in hepatic cells.
|
| 2. | Arginase catalyzes the hydrolysis of arginine to ornithine and urea.
|
| 3. | Arginase transcript variants encoding different isoforms have been found for this gene.
|
| 4. | Specifically, arginase converts L-arginine into L-ornithine and urea.
|
| 5. | Mammalian arginase is active as a trimer, but some bacterial arginases are hexameric.
|
| 6. | Arginase's active site is extraordinarily specific.
|
| 7. | Arginase deficiency, unlike other urea cycle disorders, does not entirely prevent ureagenesis.
|
| 8. | There are several arginase isozymes that differ in catalytic, molecular and immunological properties.
|
| 9. | Ammonia and arginine are thought to cause neurological problems and other symptoms of arginase deficiency.
|
| 10. | Arginase is about the enzyme reaction and has links back to both ARG1 and ARG2.
