ornithine aminotransferase feeds pyrroline-5-carboxylate exclusively into the catabolic branch of proline metabolism, which yields glutamate as an end product. Proline biosynthesis occurs predominantly or exclusively via the glutamate pathway in Arabidopsis thaliana and does not depend on glutamate produced by arginine and ornithine catabolism |

the enzyme from Toxoplasma gondii does not show a specific ornithine aminotransferase activity like its human homologue, but exhibits both N-acetylornithine and gamma-aminobutyric acid (GABA) transaminase activity (EC 2.6.1.19) in vitro, suggesting a role in both arginine and GABA metabolism in vivo |
