Function
function
Confers drought and oxidative stress tolerance mainly through enhancing ROS-scavenging capacity and Pro pre-accumulation.
Catalytic activity
- a 2-oxocarboxylate + L-ornithine = an L-alpha-amino acid + L-glutamate 5-semialdehyde
Cofactor
Pathway
Amino-acid biosynthesis; L-proline biosynthesis; L-glutamate 5-semialdehyde from L-ornithine: step 1/1.
