Citrulline depletion by ass1

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).
