The specific function of <scene name='93/934005/Spin/2'>Human ornithine aminotransferase</scene> (''h''OAT) is that of an enzyme. It can be found in humans, as well as mice and pigs. It helps transfer L-ornithine’s δ-amino group to α-ketoglutarate (α-KG). <ref>https://doi.org/10.1016/j.jbc.2022.101969</ref> There is a lack of understanding in regards to ''h''OAT's catalytic mechanism, even though it is a key component of human metabolism. As noted in the article, ''h''OAT operates on a "Bi-Bi, Ping-Pong" kinetic mechanism resulting in the first part of the reaction undergoing a conversion of PLP -> PMP and L-Orn -> L-GSA. Then PMP's amino group is catalyzed by ''h''OAT creating an α-KG.

This Sandbox is Reserved from November 4, 2022 through January 1, 2023 for use in the course CHEM 351 Biochemistry taught by Bonnie Hall at the Grand View University, Des Moines, USA. This reservation includes Sandbox Reserved 1755 through Sandbox Reserved 1764.
To get started:
  • Click the edit this page tab at the top. Click on Show preview and then Save the page after each step, then edit it again.
  • show the Scene authoring tools, create a molecular scene, and save it. Copy the green link into the page.
  • Add a description of your scene. Use the buttons above the wikitext box for bold, italics, links, headlines, etc.
