Urate Degradation to Glyoxylate

Arabidopsis thaliana
Purine nucleotides are eventually degraded to ammonia and carbon dioxide. This pathway begins in the peroxisome and follows the degradation a urate intermediate to glyoxylate. The last three steps take place in the endoplasmic reticulum. First, uricase converts urate into 5-hydroxyisourate. Steps two and three are catalyzed by the bifunctional enzyme S-allantoin synthase: the conversion of 5-hydroxyisourate into 5-hydroxy-2-oxo-4-ureido-2,5-dihydro-1H-imidazole-5-carboxylate (OHCU) and the conversion of OHCU into S-allantoin. Fourth, allantoinase requires zinc ion as a cofactor to catalyze the conversion of S-allantoin into allantoate. Next allantoate must be transported out of the peroxisome and into the endoplasmic reticulum. Fifth, allantoate amidohydrolase catalyzes the conversion of allantoate into S-ureidoglycine. This enzyme is a homodimer and requires manganese ion as a cofactor. Sixth, ureidoglycine aminohydrolase requires a manganese ion as a cofactor to catalyze the conversion of S-ureidoglycine into S-ureidoglycolate. Seventh, ureidoglycolate amidohydrolase catalyzes the conversion of S-ureidoglycolate into glyoxylate.

Urea C-13 Drug Metabolism

Homo sapiens
Urea C-13 is a drug that is not metabolized by the human body as determined by current research and biotransformer analysis. Urea C-13 passes through the liver and is then excreted from the body mainly through the kidney.

Urea Cycle

Rattus norvegicus
Urea, also known as carbamide, is a waste product made by a large variety of living organisms and is the main component of urine. Urea is created in the liver, through a string of reactions that are called the Urea Cycle. This cycle is also called the Ornithine Cycle, as well as the Krebs-Henseleit Cycle. There are some essential compounds required for the completion of this cycle, such as arginine, citrulline and ornithine. Arginine cleaves and creates urea and ornithine, and the reactions that follow see urea residue build up on ornithine, which recreates arginine and keeps the cycle going. Ornithine is transported to the mitochondrial matrix, and once there, ornithine carbamoyltransferase uses carbamoyl phosphate to create citrulline. After this, citrulline is transported to the cytosol. Once here, citrulline and aspartate team up to create argininosuccinic acid. After this, argininosuccinate lyase creates l-arginine. L-arginine finally uses arginase-1 to create ornithine again, which will be transported to the mitochondrial matrix and restart the urea cycle once more.
