Influence of zeaxanthin and echinenone binding on the activity of the orange carotenoid protein.

Biochimica et biophysica acta - 1 Apr 2009

Punginelli Claire, Wilson Adjélé, Routaboul Jean-Marc, Kirilovsky Diana

Abstract excerpt

In most cyanobacteria high irradiance induces a photoprotective mechanism that downregulates photosynthesis by increasing thermal dissipation of the energy absorbed by the phycobilisome, the water-soluble antenna. The light activation of a soluble carotenoid protein, the Orange-Carotenoid-Protein (OCP), binding hydroxyechinenone, a keto carotenoid, is the key inducer of this mechanism. Light causes structural...
