One through the glutamate pathway and the other through the ornithine pathway. Glutamate pathway plays the main role in osmotic stress and nitrogen deficiency. The ornithine pathway plays a dominant role in nitrogen abundance. In the glutamate pathway, glutamic acid (Glu) is catalyzed by pyrropridine 5-carboxylic acid synthetase (P5CS) to generate glutamyl semi-aldehyde (GSA), which is automatically cycled to pyrropridine 5-carboxylic acid (P5C), and then P5C is cycled to proline under the action of pyrropridine 5-carboxylic acid reductase (P5CR). The difference between the ornithine pathway and the glutamate pathway in the reaction is only that the substrate and enzyme of the first step of the reaction change, namely, from Glu and P5CS to ornithine (Orn) and ornithine transaminase (OAT). The degradation of proline is basically a reversal of the synthetic pathway. Proline is first oxidized to P5C by proline dehydrogenase (PDH), which generates Glu under the action of pyrrolidine -5- carboxylic acid dehydrogenase. Pathway of proline synthesis and degradation in higher plants.
