Regulation of photosynthetic light harvesting involves intrathylakoid lumen pH sensing by the PsbS protein

Li, Xiao-Ping; Gilmore, Adam; Caffari, S; Bassi, Roberto; Golan, Talila; Kramer, D; Niyogi, Krishna


The biochemical, biophysical, and physiological properties of the PsbS protein were studied in relation to mutations of two symmetry-related, lumen-exposed glutamate residues, Glu-122 and Glu-226. These two glutamates are targets for protonation during lumen acidification in excess light. Mutation of PsbS did not affect xanthophyll cycle pigment conversion or pool size. Plants containing PsbS mutations of both glutamates did not have any rapidly inducible nonphotochemical quenching (qE) and had...[Show more]
