Chlorophyll-Protein Complexes of Blue-Green Algae Isolated by a New Gel Electrophoresis System with High Resolving Power

Li Tong-zhu and Lin Shi-qing   

Abstract: At least 13 chlorophyll bands from the thylakoid membranes of blue-green algae could be clearly resolved by SDS-PAGE employing a new improved procedure. They were designated as CPIa, CPIb, CPIc, CPId, CPIe, CPIf, CPIg, CHIh, CPal, CPa2, CPa3, CPa4 and FC. 8 chlorophyll-protein complexes, CPIa-CPIh, had the same absorption spectrum at 676 nm in the red and 436 nm in the blue region. They belonged to the chlorophyll-protein complexes of PS Ⅰ. 4 chlorophyll-protein complexes, CPal-CPa4, had a red absorption peak at 670­672 nm and a blue one at 436 nm. Their fluorescence emission peak at 77K was at 685 nm. They were chlorophyll-protein complexes of PS Ⅱ.
