Citrulline depletion by ass1
WebAlthough ASS1 deficiency enhances the growth of these tumors, these cells are sensitive to depletion of external arginine. ADI-PEG20 (pegylated arginine deiminase), a modified form of a microbial enzyme, metabolizes arginine. WebTargeted disruption of this gene results in high levels of blood citrulline, hyperammonemia, and death by 24 hours after birth. Some spontaneous mutations display wrinkled skin, sparse hair with delayed hair appearance and abnormal hair follicle morphology.

WebJul 11, 2024 · Ornithine can enter the urea cycle and is converted to citrulline by ornithine transcarbamylase (OTC). Citrulline synthesizes argininosuccinate through ASS1, which in turn synthesizes arginine through ASL, thus repeating the urea cycle. Ornithine can also generate polyamines via ornithine decarboxylase (ODC).
