Protein

Delta-1-pyrroline-5-carboxylate synthase A

Gene

P5CSA

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

P5CS plays a key role in proline biosynthesis, leading to osmoregulation in plants.

Catalytic activityi

ATP + L-glutamate = ADP + L-glutamate 5-phosphate.
L-glutamate 5-semialdehyde + phosphate + NADP+ = L-glutamyl 5-phosphate + NADPH.
