  • Title: The light-harvesting chlorophylla a/b.protein complex of the green alga Acetabularia mediterranea. Isolation and characterization of two subunits.
    Author: Apel K.
    Journal: Biochim Biophys Acta; 1977 Nov 17; 462(2):390-402. PubMed ID: 412522.
    Abstract:
    In the green alga Acetabularia mediterranea a light-harvesting chlorophyll a/b.protein complex of 67 000 daltons has been found which contains two polypeptide chains of 21 500 and 23 000 daltons. These two polypeptides were isolated on a preparative scale and were further characterized by several different methods. Both polypeptides proved to be very similar. While their amino acid and sugar compositions as well as their immunochemical properties were almost identical the tryptic peptides and the cyanogen bromide fragments of the two polypeptides revealed minor but significant differences. The 67 000-dalton chlorophyll a/b.protein complex and its two polypeptide components were compared to the light-harvesting chlorophyll a/b.protein of higher plants.
