RT "Light energy allocation at PSII under field light conditions: how much
RT energy is lost in NPQ-associated dissipation?";
RL Plant Physiol. Biochem. 81:115-120(2014).
CC -!- FUNCTION: Involved in high light-mediated energy-dependent
CC nonphotochemical quenching (NPQ, qE) and thermal dissipation (TD) thus
CC regulating energy conversion in photosystem II and protecting from
CC photoinhibition (By similarity). Seems also to regulate quantum yield
CC of electron transport in fluctuating light conditions (By similarity).
CC {ECO:0000250|UniProtKB:Q0J8R9}.
CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane
CC {ECO:0000250|UniProtKB:Q9XF91}; Multi-pass membrane protein
CC {ECO:0000255}.
CC -!- SIMILARITY: Belongs to the ELIP/psbS family. {ECO:0000305}.
