CC   -!- FUNCTION: Water-soluble antenna for capture of solar energy in the
CC       blue-green range. Peridinin is an asymmetric carotenoid.
CC   -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC       Absorption:
CC         Abs(max)=~480 nm;
CC   -!- SUBUNIT: Homotrimer.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast.
CC   -!- DOMAIN: The mature protein is composed of 2 almost identical repeat
CC       units.
