Pigment structure in the violaxanthin–chlorophyll-a-binding protein VCP

Resonance Raman spectroscopy was used to evaluate pigment-binding site properties in the violaxanthin–chlorophyll-a-binding protein (VCP) from Nannochloropsis oceanica. The pigments bound to this antenna protein are chlorophyll-a, violaxanthin, and vaucheriaxanthin. The molecular structures of bound Chl-a molecules are discussed with respect to those of the plant antenna proteins LHCII and CP29, the crystal structures of which are known. We show...
