Protein
Protein SUPPRESSOR OF QUENCHING 1, chloroplastic
Organism
Arabidopsis thaliana
Function
Required to maintain light harvesting efficiency, especially during nonphotochemical quenching (NPQ) recovery, via the regulation of chlorophyll excited-state lifetime probably by preventing the formation of a slowly reversible form of antenna quenching.
Similarity
In the C-terminal section; belongs to the thioredoxin family.
