| 摘 要： | In fresh Porphyra yezoensis, R-phycoerythrin exists mainly as octamer (αβ)_8 with only a small percentage of dimer (αβ)_2.The octamer could be dissociated into dimer in the presence of oxygen and visible light.The dimer was ultracentrifuged in a sucrose linear gradient to obtain the monomer,The monomer could be associated again into dimer.This reversible change between the monomer and dimer of R-phycoerythrin may be attributed to the shift of hydrogen bonds between forms of phycoerythrin molecules.
