Protein

Serine/threonine-protein kinase stt7, chloroplastic

Gene

STT7

Organism
Chlamydomonas reinhardtii (Chlamydomonas smithii)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Serine/threonine protein kinase required for state transition by phosphorylating light-harvesting complex II outer antennae (LCHII). State transition plays a central role in response to environmental changes and allows to adjust to changing light conditions via the redistribution of light excitation energy between photosystem II (PSII) and photosystem I (PSI).1 Publication

Catalytic activityi

ATP + a protein = ADP + a phosphoprotein.
