摘要
与菠菜(Spinacia oleracea)类囊体混匀保温,藻胆蛋白可以将其所吸收的光能传递给菠菜的PSⅡ,但传能效率因藻胆蛋白的种类而异。若用青菜(Brassica chinensis)类囊体,则仅当别藻蓝蛋白存在时,藻红蛋白或藻蓝蛋白才能将其所吸收的光能传递给PSⅡ。
The excited energy transfer from phycobiliproteins to thylakoids of higher plants was investigated.When incubated with spinach thylakoids,phycobiliproteins isolated from red and blue-green algae have transferred the light energy which they absorbed to spinach PS Ⅱ .The efficiency of energy transfer dependent upon the kind of phycobiliproteins used.If spinach thylakoids were replaced by thylakoids of Brassica chinensis;R-phycoerythrin or Cphycocyanin could transfer the excited energy to PS Ⅱ of B.chinensis only in the presence of allophycocyanin.
