Ser238 is essential for ensuring differential effects of chloride anions and proline on the activity of Arabidopsis thaliana δ1-pyrroline-5-carboxylate reductase.
Results showed the abolishment of most differences when using either nicotinamide adenine dinucleotide as the cosubstrate or NADH or NADPH as the cosubstrate, which represents a first step toward protein engineering aiming at modulating proline biosynthesis under stress.
