| 11. | One in 70000 adults has an ornithine transcarbamylase deficiency.
|
| 12. | Specifically, arginase converts L-arginine into L-ornithine and urea.
|
| 13. | Mutations in the " SLC25A15 " gene cause ornithine translocase deficiency.
|
| 14. | Ornithine aminotransferase forms the initial intermediate in this process.
|
| 15. | The separate pathways of converting ornithine to putrescine in plants and animals have converged.
|
| 16. | Biochemically, it can be detected by elevated levels of ornithine in the blood.
|
| 17. | These are lysine, arginine, and ornithine.
|
| 18. | Biosynthesis begins with decarboxylation of ornithine by ornithine decarboxylase ( ODC ) to produce putrescine.
|
| 19. | Biosynthesis begins with decarboxylation of ornithine by ornithine decarboxylase ( ODC ) to produce putrescine.
|
| 20. | Ornithine decarboxylase can catalyse the decarboxylation of DFMO instead of ornithine, as shown above.
