Abstract excerpt

Monodehydroascorbate reductase (MDAR; EC 1.6.5.4) is crucial for AsA regeneration and essential for maintaining the reduced pool of AsA. And the amino acid residue C117 of chloroplastic MDAR is the conserved cysteine residue in MDAR isoforms. A series mutation of conserved amino acid residue cysteine117 (C117) was constructed to investigate its role in MDAR structural stability and activity. Our study revealed...
