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

The Journal of biological chemistry - 28 May 2004

Abstract excerpt

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. Mutatio...
