Abstract
A chlorophyll ac-fucoxanthin light-harvesting protein has been separated by SDS-polyacrylamide gel electrophoresis and by digitonin-sucrose density centrifigation from thylakoids of Pavlova lutherii. It contains a single major polypeptide of 21 kDa, comprises 69% of the total chlorophyll a and is enriched in chlorophyll c compared to the thylakoids. Energy transfer from chlorophyll c and fucoxanthin to chlorophyll a was demonstrated within the protein complex. Antibodies to the 21 kDa apoprotein showed cross-reactivity with the 26–28 kDa apoproteins of higher plant light-harvesting chlorophyll a b protein and with the 19 kDa apoprotein of the light-harvesting complex of diatoms, but much reduced or no cross-reactivity with the major thylakoid polypeptides of dinoflagellates and cryptophytes.
