Ornithine-delta-aminotransferase is essential for arginine catabolism but not for proline biosynthesis.

BMC plant biology - 17 Apr 2008

Funck Dietmar, Stadelhofer Bettina, Koch Wolfgang

Abstract excerpt

BACKGROUND: Like many other plant species, Arabidopsis uses arginine (Arg) as a storage and transport form of nitrogen, and proline (Pro) as a compatible solute in the defence against abiotic stresses causing water deprivation. Arg catabolism produces ornithine (Orn) inside mitochondria, which was discussed controversially as a precursor for Pro biosynthesis, alternative to glutamate (Glu). RESULTS: We show here...
