The specific function of ornithine aminotransferase is responsible for converting ornithine into pyrroline-5-carboxylate (P5C) to another molecule. Glutamate and proline are the amino acids that can be produced from P5C

Homo sapiens is the organism from which the HOAT is derived
 +
 
 +
These enzymes are comprised of substrates - L-Orn, GABA and AVA. By using the soaking method, the GABA structure was covalently attached to the PLP, as well as the AVA structure. Both structures were covalently attached to both the PLP and Catalytic Lys292.

 +
A type of cancer that is being studied is hepatocellular carcinoma, an aggressive form of liver cancer. Scientists have determined that HOAT is over-expressed in specific cells.
 +
 
 +
The study of the HOAT enzyme has enabled scientists to gain a more thorough understanding of metabolism. This is because it provides information about how the human body responds to specific stimuli through the use of this enzyme.

Each C=O consists of two oxygen atoms that form hydrogen bonds, which stabilize the secondary structure. A polar amino acid residue is on the outside and a nonpolar amino acid is inside the alpha helix since non-polar amino acids do not react with water. Beta sheet runs in an antiparallel direction of non-polar and polar amino acids.

<scene name='93/934000/Aa_aromatic/1'>Aromatic rings</scene> plays a role important role in protein structure and ligand binding. Aromatic ring is important of protein interaction that allows pi stacking and acts as acceptor for hydrogen bonds. It is important for protein structure and ligand binding.

Polar amino acids</scene> is important part of protein structure. It is found usually on the outside of the alpha and beta that is because of its water-loving quality. It help to determine the 3-D structure and its specifically function.
