PSA2

Protein PHOTOSYSTEM I ASSEMBLY 2, chloroplastic

196 amino acids

Nuclear genome-encoded factor required for the accumulation of photosystem I (PSI) during plant development. May form a complex with PSAG and mediate thiol transactions in the thylakoid lumen that are important for the assembly of PSI. Possesses protein-disulfide reductase activity in vitro.
