摘要
具有不同聚集态的藻胆蛋白有着不同的摩尔消光系数。这些聚集态决定了引起各藻胆蛋白之间光谱特性差别的藻蓝胆素发色团的构象。研究结果表明,在高聚态的C-藻蓝蛋白和变藻蓝蛋白中,由蛋白质——发色团之间相互作用调制的发色团的构象,对太阳能的吸收和激发能转移到光合反应中心的过程可能有重要作用。
Phycobiliproteins with different aggregations have different molar excitinction coefficients. The assembling states lead to the different conformations of phycocyanobilins chromophores in C-phycocyanin and allophycocyanin which cause different spectral properties. As a result, on the higher aggregations for C-phycocyanin and allophycocyanin, the conformations of phy-cocyanobilin chromophores modulated through protein-chromophore interaction may play an important role in solar energy harvesting and excitation energy migration from these antenna proteins to photosynthetic reaction centers.
