DELTA-OAT ornithine-delta-aminotransferase [Arabidopsis thaliana (thale cress)] - Gene

Summary

Official Symbol: DELTA-OAT
Official Full Name: ornithine-delta-aminotransferase
Primary source: TAIR:AT5G46180
Locus tag: AT5G46180
See related: Araport:AT5G46180
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Arabidopsis thaliana (ecotype: Columbia)
Lineage: Eukaryota; Viridiplantae; Streptophyta; Embryophyta; Tracheophyta; Spermatophyta; Magnoliopsida; eudicotyledons; Gunneridae; Pentapetalae; rosids; malvids; Brassicales; Brassicaceae; Camelineae; Arabidopsis
Also known as: MCL19.24; MCL19_24; ornithine-delta-aminotransferase
Summary: Encodes an ornithine delta-aminotransferase that is transcriptionally up-regulated in young seedlings and in response to salt stress. It is unlikely to play a role in salt-stress-induced proline accumulation, however, it appears to participate in arginine and ornithine catabolism.
