Protein

Photosystem II 22 kDa protein, chloroplastic

Gene

PSBS

Organism
Solanum sogarandinum
Status
Reviewed-Annotation score: Annotation score: 2 out of 5-Experimental evidence at transcript leveli

Functioni

Seems to be involved in non-photochemical quenching, a process maintains the balance between dissipation and utilization of light energy to minimize generation of oxidizing molecules, thereby protecting the plant against photo-oxidative damage.By similarity
