Compartmentation of Arg and Pro metabolic pathways. δOAT links the degradation pathways for Arg and Pro, which converge at the level of P5C in mitochondria. Pro biosynthesis occurs in the cytosol or, during stress, in plastids, whereas Arg biosynthesis is constitutively localised in plastids. For details on Arg biosynthesis up to Orn see [3]. ASL: argininosuccinate lyase; ASSY: argininosuccinate synthetase; OTC: ornithine transcarbamylase, P5C: pyrroline-5-carboxylate, P5CDH: P5C dehydrogenase; P5CR: P5C reductase; P5CS: P5C synthetase, ProDH: Pro dehydrogenase.
