Outline of Final Research Achievements |
Among prokaryotes, only two genera of cyanobacteria have α-carotene. α-Carotene had opposite chirality, (6′S) in Acaryochloris and normal (6′R) in Prochlorococcus. This is the first natural occurrence of (6′S)-α-carotene. All the zeaxanthin in these species were usual (3R,3′R)-chirality. Carotenoid compositions in Rhodophyta are divers. Rhodophyta is divided into two groups, unicellular (Cyanidiophyceae, Porphyridiophyceae, Stylonematophyceae and Rhodellophyceae) and macrophytic algae (Compsopogonophyceae, Bangiophyceae and Florideophyceae). All of unicellular algae contained only β-carotene and zeaxanthin (ZEA-type). Compsopogonophyceae contained ZEA-type and additional antheraxanthin (ANT-type), while Bangiophyceae contained ZEA-type and additional α-carotene and lutein (LUT-type). Consequently, relation between carotenoid compositions and phylogenetics of Rhodophyta was found. Therefore, diverse carotenoid compositions can be explained presence or absence of the enzymes.
