Metabolite Identification
Common NameD-Ornithine
DescriptionD-Ornithine belongs to the class of organic compounds known as d-alpha-amino acids. These are alpha amino acids which have the D-configuration of the alpha-carbon atom. D-Ornithine is possibly soluble (in water) and a very strong basic compound (based on its pKa). D-Ornithine can be converted into 5-amino-2-oxopentanoic acid through its interaction with the enzyme D-amino-acid oxidase. In cattle, D-ornithine is involved in the metabolic pathway called the D-arginine and D-ornithine metabolism pathway.

General function:
Involved in ornithine decarboxylase inhibitor activity
Specific function:
Ornithine decarboxylase (ODC) antizyme protein that negatively regulates ODC activity and intracellular polyamine biosynthesis and uptake in response to increased intracellular polyamine levels. Binds to ODC monomers, inhibiting the assembly of the functional ODC homodimer, and targets the monomers for ubiquitin-independent proteolytic destruction by the 26S proteasome. Triggers ODC degradation by inducing the exposure of a cryptic proteasome-interacting surface of ODC. Stabilizes AZIN2 by interfering with its ubiquitination. Also inhibits cellular uptake of polyamines by inactivating the polyamine uptake transporter. SMAD1/OAZ1/PSMB4 complex mediates the degradation of the CREBBP/EP300 repressor SNIP1. Involved in the translocation of AZIN2 from ER-Golgi intermediate compartment (ERGIC) to the cytosol.
