The light‐harvesting chlorophyll a‐c‐binding protein of dinoflagellates: a putative polyprotein

Abstract
The principle light‐harvesting chlorophyll a‐c‐binding protein of Amphidinium carterae of 19 kDa is encoded as a polyprotein translated from a 6.1 kb mRNA. The cDNA sequences indicate that each derived polypeptide is contiguous with the next and that the mature peptides are formed by cleavage at a C‐terminal arginine residue. Comparison of the amino‐acid sequences shows the Amphidinium protein to be most closely related to the fucoxanthin‐chlorophyll‐protein (Fcp) of Phaeodactylumand less related to the chlorophyll a‐b‐binding (Cab) proteins including those from Euglena.
