- Peridinin
Peridinin is a light-harvesting
carotenoid , apigment related tochlorophyll which appears in theperidinin-chlorophyll-protein (PCP)light-harvesting complex indinoflagellate s, best studied in "Amphidinium carterae ". The PCP complex is unique in its high ratio of peridinin to chlorophyll; most light-harvesting complexes contain more chlorophyll than other carotenoids, but the PCP contains eight peridinin and two chlorophyll molecules arranged to promote peridinin-chlorophyll energy transfer. The PCP complex is aprotein trimer with an unusualalpha solenoid protein fold.References
