Abstract

The reassociation of carotenoids with the photosynthetic light-harvesting 1 (LH1) pigment– protein complex has proven to be a powerful technique to investigate the function of carotenoids. We have recently investigated the reassociation of the carotenoids, spirilloxanthin (number of conjugated C= C bonds (n)= 13), anhydrorhodovibrin (n= 12), rhodopin (n= 11), and spheroidene (n= 10)) with carotenoid-depleted LH1 subunits ...
