Also known as
CP22; NONPHOTOCHEMICAL QUENCHING 4; PHOTOSYSTEM II SUBUNIT S; PSBS; PSII-S; T18F15.3; T18F15_3
Summary
Encoding PSII-S (CP22), a ubiquitous pigment-binding protein associated with photosystem II (PSII) of higher plants. Involved in nonphotochemical quenching rather than in photosynthesis. Mutant has a normal violaxanthin cycle but has a limited capacity of quenching singlet excited chlorophylls and is tolerant to lipid peroxidation.
