Carbamoylphosphate synthetase 1 (CPS1) is the first enzyme of the urea cycle. CPS1 deficiency is a rare autosomal-recessively inherited disorder that can lead to life-threatening hyperammonemia. Since there is no reliable biochemical marker for this disease, diagnosis relies on molecular

The pseudo-reverse reaction of Pseudomonas aeruginosa catabolic ornithine carbamoyltransferase in which arsenate is first coupled to citrulline followed by elimination of carbamylarsenate has been studied. Arsenate and citrulline saturation curves are sigmoidal. The different responsiveness of the transcarbamoylase to isosteric

Ornithine transcarbamylase (OTC; EC 2.1.3.3) is a one-carbon-unit transferring enzyme that synthesizes citrulline using ornithine and carbamoylphosphate as substrates. It is involved in the metabolic transformation of arginine and proline, and it participates in the urea cycle in vertebrates and

Free ammonium ions are produced and consumed during cell metabolism. Glutamine synthetase utilizes free ammonium ions to produce glutamine in the cytosol whereas glutaminase and glutamate dehydrogenase generate free ammonium ions in the mitochondria from glutamine and glutamate, respectively. Ammonia

For bioartificial liver application, cells should meet the following minimal requirements: ammonia elimination, drug metabolism and blood protein synthesis. Here we explore the suitability of HepaRG cells, a human cell line reported to differentiate into hepatocyte clusters and surrounding biliary
