Ser238 is essential for ensuring differential effects of chloride anions and proline on the activity of Arabidopsis thaliana δ1-pyrroline-5-carboxylate reductase
{{output}}
Many plant species accumulate proline as a mechanism to withstand various abiotic stress conditions. Proline synthesis proceeds from either glutamate or ornithine, but in both pathways the last step is catalysed by a δ1-pyrroline-5-carboxylate (P5C) reductase... ...
